8x-4y=16

y=2x-4

8x-4(2x-4)=16

8x-8x+16=16

0x+16=16

so what do i do now?

**Damon**, Tuesday, December 11, 2007 at 7:00pmThose two equations are the same.

Look at your first equation dividing both sides by 4

2 x - y = 4 or y = 2x-4 which is the second equation exactly. There is no intersection of a line with itself in a point. The system of two equations given has no solution.
