Question

Solve this system of linear equations.

6x+6y=0
-10x+4y=28

Answer 1

divide first equation by 6 (both sides) and second - by 2
you'll have:
x+y=0
-5x+2y=14
right?

Answer 2

from the first one you can get:
y=-x
substitute y for (-x) in second:
-5x +2*(-x)=14
solve it for x

Answer 3

-7x=14
x=-2
from the first equation we know that y=-x
so, y=2
the answer:
x=-2, y=2
or (-2,2)

Answer 4
