Solve by substitution.

y=.8x+72
20x+32y=48

How do you get y? i got the x part but i can't seem to get the y part.

solve this:
20x+32 (.8x+72)=48
then, you have x. Then solve y=.8x+72

i actually wrote the second part wrong. Its supposed to be y=.8x+7.2 not 72. and when i solved it i got 10.4 for y and my x is 4.

Is it right?
