Question

Graph by substitution -5x+3y=12
x+2y=8

Answer 1

Graph or solve by substitution? o-o

Answer 2

Oops solve

Answer 3

yes it is

Answer 4

lol what

Answer 5

-5x+3y=12
x+2y=8 x=8-2y

plugging that x=8-2y in the first equation's x will give the answer but if you want to continue..
-5(8-2y) + 3y = 12
-40 +10y + 3y = 12
13y = 52
y = 4 x=0 (when you put in y=4 in x+2y=8, you get x=0)

hope that helped :D
