Answer:
x = 3
Step-by-step explanation:

m = slope
x, y = coordinates

15x-3y=12
<u>y=5x—4
</u>I'm also not sure what your question is, but this is what I got by solving it like a regular equation.
15x-3(5x-4)=12
15x-15x+12=12
0=12-12
0=0
4x-y=-4
<span><u>-8x+2y=2</u>
</span>
-y=-4-4x /: (-1)
y=4+4x
-8x+2y=2
-8x+2(4+4x)=2
-8x+8+8x=2
0=-6
