After you get the equations: 3x + 4y =40 and 5x + 2y =34, use matrices and plug it into the graphing calculator which will give you the answers for x and y.
X is going equal to 4
and y is going to equal 7
check:
3(4) + 4(7)= 40
5(4) + 2(7)= 34
btw... never knew this is college level mathematics ^_^
