To answer the problem you take 13 and minus -2 to get 15 and divide 15 by 5/4 and you get 12.
Hope I help. :)
X and y
x=2y+9
x-y=22
*x is the larger number*
plug in x to solve for y
2y+9-y=22
y+9=22
-9 both sides
y=13
plug in y and solve for X
x=2 (13)+9
x=26+9
x=35
I think that it might be "c" but I am not sure but hey it is worth a shot sorry if I am wrong!
