Step 1

Try to eliminate a variable as you add the left sides and the right sides of the two equations

Step 2

Set the sum resulting from adding the left sides equal to the sum resulting from adding the right sides

Step 3

Solve for the variable that was not cancelled or eliminated

Step 4

Use the answer found in step 3 to solve for the other variable by substituting this value in one of the two equations
