In Excel, we often need to **solve equations for x**, which is the root of the equation. Finding the root of an equation can be quite simple for linear equations. But as you try to find the roots of a **quadratic equation,** **cubic equation,** or equations with higher degrees of x, it becomes more difficult and, in some cases, almost impossible. However, Excel is here to save you from all of these problems. Excel makes it quite simple for us to **solve equations for x**. In this article, we will learn 2 simple yet efficient ways to **solve for x in Excel**.

## 2 Simple Methods to Solve for x in Excel

The following dataset has **4 **equations, each of which successively increases the power of x. Our goal is to find the value of **x **in these equations.

Not to mention that we have used *Microsoft Excel 365 *version for this article, you can use any other version according to your convenience.

### 1. Using Goal Seek Feature to Solve for x in Excel

Using the **Goal Seek** feature, a tool of the **What-If Analysis**, is one of the easiest ways to solve for **x **in Excel.Â It searches for a specified value of a cell by changing the value of one cell. In this case, the **Goal Seek** feature will try to find for which the value of **x**, the value of the equation, becomes **0**. Letâ€™s follow the steps mentioned below to do this.

** â™¦ Step 01: Formulate the Equation to find F(x) ValueÂ Â **

- Firstly, enter the following formula in cell
**C5**.

`=(20*D5)-307`

Here, cell **D5 **refers to the cell of **X Value** column.

- Following that, press
**ENTER**.

** Note:** Here, we will be using the cells in

**Column D**as our initial

**x**value. As, in the beginning, there are no values in those cells, the initial

**x**values will be

**0**for all the cases.

As a result, you will see the following output in cell **C5**, as marked in the following image.

- Now, enter the following formula in cell
**C6**to find the**F(x) Value**for the second equation.

`=(D6^2)-(7*D6)+2`

Here, cell **D6 **represents the cell of *X Value* column.

- Next, hit
**ENTER**.

Consequently, you will get the **F(x)** **Value **for the second equation.

- Following the same process, you can find the
**F(x) Values**for the rest of the equations.

**â™¦Â Step 02: Choose Goal Seek Feature**

- Firstly, go to the
**Data**tab from**Ribbon**. - Following that, select the
**What-If Analysis**option. - Now, choose the
**Goal Seek**option from the drop-down.

Subsequently, the **Goal Seek** dialogue box will open as shown in the following image.

- Now, click on the box of
**Set cell**and select cell**C5**as marked in the image given below. - After that, enter
**0**in the**To Value**box

- Following that, click on the
**By changing cell**box and choose cell**D5**. - Then, click on
**OK**.

Subsequently, the **Goal Seek Status** dialogue box will be visible and confirm that it has found a solution.

- Finally, click
**OK**.

As a result, you will get the **x Value** for the first equation as demonstrated in the following picture.

- Now, by following the same procedure, you will get the rest of the
**x Values**for other equations.

### 2. Utilizing Solver Add-in to Solve for x in Excel

Utilizing the **Solver Add-in** option of Excel is another efficient way to solve an equation for **x**. By default, the **Solver Add-in** feature is not enabled. Letâ€™s use the steps to solve an equation for x in Excel.

**â™¦Â Step 01: Enable the Solver Add-in**

- Firstly, use the keyboard shortcut
**ALT + F + T**to open the**Excel Options**dialogue box from your worksheet.

- After that, go to the
**Add-ins**tab from the**Excel Options**dialogue box. - Then, click on the
**Go**option as marked in the following image.

- Next, check the box
**Solver Add-in**option. - Afterward, click
**OK**.

- Following that, go to the
**Data**tab and you will see that the**Solver**option is added to the**Analyze**group.

**â™¦Â Step 02: Formulate the Equation to find F(x) Value**

- Use the
**procedure mentioned in Step 01 of the first method**to get the**F(x) Values**for the equations.

**â™¦Â Step 03: Utilizing the Solver Add-in Option**

- Firstly, go to the
**Data**tab from**Ribbon**. - Next, choose the
**Analyze**option. - Then, select the
**Solver**option from the drop-down.

As a result, the **Solver Parameters **dialogue box will open on your worksheet as shown in the following picture.

- After that, click on the marked option like in the following image.

- Subsequently, choose cell
**C5**under column**F(x) Value**.

- Now, in the
**Solver Parameters**dialogue box, choose the**Value**of option and enter**0**in the marked box. - After that, click on the marked option in the following picture.

- After that, select cell
**D7**and click on the marked region of the following image.

- Following that, click on
**Solve**.

Consequently, Excel will give confirmation that the solver has found a solution.

- Finally, click on
**OK**from the**Solver Results**dialogue box.

As a result, you will find the **x Value** for the first equation.

** Note:** Here, the

**F(x) Value**in cell

**C5**represents that the value is close to

**0**.

- Next, by using the same steps, you can get the
**x Values**for the remaining equations.
