So, I need to solve these two problems, graph them on a map and determine the coordinates.

Question

x+2y=-6
2x-4y=-4

A. (4,-4)
B. (-3,4)
C. (-4,-1)
D. (-2,9)
E. No solution

Answer 1

divide the second equation by 2, then add to the first equation. I get
2x=-6=2
x=-4
now put that into the first equation, and solve for y.
