Solve the system of equations.

Brums [2.3K]

Solve the system of equations.
12x + 3y = 12
-6x +y = -26

A) (-3,9)
B (-6, -9)
© (-3,8)
D (3, -8)

12x + 3y = 12
2(-6x +y = -26)

12x + 3y = 12
-12x + 2y = -52

—-now x cancels out

5y/5 = -40/5

y = -8

The answer should be D. Let me know if you got it right.
