## How do you solve a system of linear equations by substitution?

1. Step 1 : First, solve one linear equation for y in terms of x .
2. Step 2 : Then substitute that expression for y in the other linear equation.
3. Step 3 : Solve this, and you have the x -coordinate of the intersection.
4. Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.

How do you teach systems by substitution?

Step 1: Solve one equation for one of the variables. Step 2: Substitute the resulting expression into the other equation to replace the variable. Then solve the equation. Step 3: Substitute to solve for the other variable.

### How do you make a system of equations fun?

What’s the substitution method?

One method to look at is called the substitution method. You solve one equation for one variable and then substitute this expression into the other equation. In the substitution method you solve for one variable, and then substitute that expression into the other equation.

#### How do you create a system of equations?

Here’s how it goes:

1. Step 1: Solve one of the equations for one of the variables. Let’s solve the first equation for y:
2. Step 2: Substitute that equation into the other equation, and solve for x.
3. Step 3: Substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

What is the formula of substitution method?

The substitution method is a simple way to solve linear equations algebraically and find the solutions of the variables. As the name suggests, it involves finding the value of x-variable in terms of y-variable and then substituting or replacing the value of x-variable in the second equation.
