What method does this describe?
Step 1: Make sure the equations are lined up!
Step 2: ADD or SUBTRACT _ the equations to eliminate
the variable with common COEFFICIENTS
Step 3: SOLVE for the remaining variable.
Step 4: SUBSTITUE _your answer into either original
equation and SOLVE for the other variable.
