The answer is A
Multiply the 2nd equation by -2
-2x -12y = -8
Then add it to the 1st equation
-9y = -6
y = 2/3
By substituting in the 1st equation
2x + 3(2/3) = 2
2x = 0
x=0

Answer:
x=-2
Step-by-step explanation:
Step 1: Subtract 8x from both sides.
5x+6−8x=8x+12−8x
−3x+6=12
Step 2: Subtract 6 from both sides.
−3x+6−6=12−6
−3x=6
Step 3: Divide both sides by -3.
−3x
−3
=
6
−3
x=−2
