Step 2: Add the equations vertically.
Now that we've created terms that are opposites, one of the variables will cancel out when we add the equations.
Step 3: Solve for the first variable.
The y terms canceled, so we can solve the equation that's left.
Step 4: Solve for the second variable.
Go back to one of the original equations (you can choose either one) and plug in 8 for x.
Step 5: Write answer as ordered pair.
Make sure to put the variables in alphabetical order when you write the ordered pair.
Step 6: Check your answer.
Use the original equation that you didn't use earlier. If you use the same equation twice, it will not find a mistake.
