Question

please refresh me on substitution method:
8x-3y=8
7x+4y+60

Answer 1

8x-3y = 8

y = (8-8x)/-3

put that into either equation

Answer 2

oh, I remember that. lemme see if I can work it out

Answer 3

well, I've gotten it to x = 8+3y/8
and 7(8+3y/8) +4(8+3y/8)
right so far?

Answer 4

can someone help with my problem? please

Answer 5

oops, except I just used an x in place of a y on the 4, so ignore that.
