No that's not it.
I'd like to point out that AMHD is not a chat site and you sometimes have to wait before you get an answer.
The easiest way to solve your equations is by equating them (similar to substitution).
y=3x-8
y=4-x
Which means that :
y=3x-8 =4-x
Hence:
3x-8 =4-x
Then you solve for x.
If you want to go for elimination, then subtract the second equation from the first:
y = 3x - 8
y = -x + 4
0 = 4x - 12
Then you go from there to solve for x.
When you get x, use that value to solve for y.
