STEP 1: Multiply second equation by -3.
After multiplying we have the following system:
3x+4y−3x+3y=8=−36
STEP 2: add the two equations together to eliminate x from the system.
7y=−28
STEP 3: find y
<u>y=−4</u>
<u></u>
STEP 4: substitute the value for y into the original equation to solve for x.
3x+4(−4)=8
<u>x=8</u>
