Answer:
[tex]\boxed{x = -2~~and~~ y = -4}[/tex]
Step-by-step explanation:
-2x + 2y = -4 (times 3) -6x + 6y = -12
3x + 3y = -18 (times 2) 6x + 6y = -36
.
-6x + 6y = -12
6x + 6y = -36 +
12y = -48
[tex]y = \frac{-48}{12}[/tex]
y = -4
.
Substitute the value of y to the one of equations
-2x + 2(-4) = -4
-2x - 8 = -4
-2x = -4 + 8
-2x = 4
[tex]x = \frac{4}{-2}[/tex]
x = -2
