## What is a Substitution Calculator?

Substitution calculator with steps is an online digital tool that enables you to **find the value of two variables** using the substitution method. It determines the variables' values from the given linear system equation in a couple of seconds.

## Substitution Method:

The substitution method is the commonly used method in algebra to find the **value of a pair of variables** when one variable (x variable value) is isolated from one equation. Then you put the variable value into the second equation to find the second variable (y variable value).

After finding y, substitute the y value of the equation to get the value of the first variable.

## Formula Behind Substitution Method Calculator:

The substitution method consists of a system of linear equations where a pair of variables is involved. The substitution calculator uses the following **formula to solve the system of equations by substitution**.

Whereas,

$$ ax^1 + by^1 \;=\; c^1 $$

$$ ax^2 + by^2 \;=\; c^2 $$

## Can Substitution Math Calculator Give Solution in Steps?

Yes, our substitution method calculator gives the solution in steps. Our tool has advanced features that enable you to find the solution of linear equation variables.

Let’s understand how the substitute calculator solves the system of equations problem by substitution:

## Working of System of Equations Calculator Substitution:

When you add two equations in the substitute method calculator, it checks the given linear equation. After checking, it knows which variable is separated from the equations (either x or y variable).

Then isolated variable value is substituted in the second equation to find the variable value. Suppose you want to find the value of x, therefore **substitute the y value** in the given equation. After simplification, you will get the solution of the x variable.

Now substitute the x value in one of the given equations to find the y variable value. Substitution math calculator provides you solution of a linear equation of both the variables (x or y value).

Now check your answer, you can **add x and y values** in one of the given equations or both equations. Then simplify it, if the left-hand side and right-hand side are equal then your roots are correct, if not then again check your solution.

To avoid all this hassle, the substitution calculator with steps gives you the exact solution as per your input immediately.

## Solve by Substitution - An Example

The system of equations calculator substitution can be used to solve the substitution problems easily but it’s crucial to know the manual calculations. So an example is given below,

### Example:

Solve the system by substitution,

\begin{matrix} -x & +y & =\;-5 \\ 2x & -5y & =\; 1 \\ \end{matrix}

**Solution:**

First, it separates the y value from equation 1 as:

$$ -x + y \;=\; -5 $$

$$ y \;=\; x - 5 $$

Now substitute the y = x + 5 value into equation 2 to get the value of x.

$$ 2x - 5y \;=\; 1 $$

$$ 2x - 5(x-5) \;=\; 1 $$

$$ 2x - 5x + 25 \;=\; 1 $$

$$ -3x \;=\; -24 $$

$$ x \;=\; 8 $$

Substitute the x = 8 value of one of the given equations to get the value of y.

$$ -(8) + y \;=\; -5 $$

$$ y \;=\; 3 $$

So the solution is (8, 3).

Now combine the both equations and solve by substitution

$$ -x + y \;=\; -5 $$

$$ -(8) + (3) \;=\; -5 $$

$$ 2x - 5y \;=\; 1 $$

$$ 2(8) - 5(3) \;=\; 1 $$
