Yea his answer is right ^^
Your going to want to first distribute the negative out to the second equation
65x+50y-16x+21y
49x+71y
Divide 4 and 5/8 by 5/8. you will get 7 and 2/5, or 7.4. since this you need whole pieces of wood, round down to 7.
final answer=7 pieces of wood
Ax + By = C
3x + 2y = 12
A=3, B = 2 and C = 12
