Answer 3

lol can u figure out based on this? @ashleysmith ?

Answer 4

i got 8x+8y=0

Answer 5

how do i get x and y

Answer 6

well if 8x and 8y equal zero, there is an automatic assumption that both variables equal zero as they do not produce a value other than zero... but you check by solving for each variable.

Answer 7

8x+8y=0
-8x -8x
--------
8y=-8x+0
/8 /8 /8
--------
y=-x+8
y=0 because solving for x would yield the same thing, so
x also equals y. Does that make sense @ashleysmith ?
