Solving Systems of Linear Equations

Renata Eley
Substitution Method

This is the problem, write it down first.

Step 1: Solve for one variable.

In this case I solved for X first as you can see in the example above.

Step 2: Solve for the second variable.

For my second variable I plugged in X and got the second variable Y.

Step 3: Write the solution.

In the picture above I plugged in X and Y .

Step 4: Check your solution.

The last step I plugged in and solved. My answer came out both the same.
