I need to know how to solve 2x-4y=14 and -4x+8y=6 by elimination

Question

So far I have x=7(don't remember how I got that) but I try to plug it in to one of the equations and I just don't know how.

Answer 1

2x - 4y = 14

-4x + 8y = 6

Look at this set of equations again! CAREFULLY!!!!

Divide the 2nd equation by -2: 2x - 4y = -3

Do the lines for these equations intersect? What does that mean?
