Answer:
C, (12, -1)
Step-by-step explanation:
x - 2y = 14
x + 3y =9
Add 2y to both sides
x = 14 +2y
Substitute this into the second equation and solve
14 + 2y + 3y = 9
5y = 9 - 14 = -5
5y = -5
y = - 1
(you don't need to do this step because there is only one equation with y=-1, but just in case...)
Plug y into the first equation:
x - 2(-1) = 14
x - (-2)= x+2
x + 2 =14
x =12
Therefore, the answer is (12, -1)
The answer is C
