Answer:
(6, -9)
Step-by-step explanation:
(Equation 1) 6x + 2y = 18
(Equation 2) -4x - 2y = -6
Rearrange Equation 1 to find (the equation for) y
6x + 2y = 18
-6x + 18 = 2y
-3x + 9 = y
Therefore y = -3x + 9
Substitute y into Equation 2
-4x - 2(-3x + 9) = -6
-4x + 6x - 18 = -6
2x - 18 = -6
2x = -6 + 18
2x = 12
x = 6
Substitute x into the equation for y
y = -3x + 9
y = -3(6) + 9
y = -18 + 9
y = -9
