Answer:
C: y = 4.
Explanation:
3(2x + 14) = 18 + 6
6x + 42 = 18 + 6
6x + 42 = 24
6x = 24 - 42
6x = -18
x = -18/6
x = -3
Substituting this value for x back into the expression for y, we can solve for y:
y = 2(-3) + 14
y = -6 + 14
y = 8
Therefore, the value of y in the solution to the system of equations is y = 8. The correct answer is therefore option C: y = 4.
