Solve for y in the equation 3y – 9 = 18.

-3
3
6
15

The correct answer is: 6

To solve for y in this equation, we need to isolate the variable by performing the opposite operations. In this case, we need to first add 9 to both sides to get 3y = 27. Then, we divide both sides by 3 to get y = 9. Therefore, the correct answer is C. Option A, -3, is incorrect because if we substitute -3 into the equation, we get 3(-3) - 9 = -18 - 9 = -27, which is not equal to 18. Option B, 3, is incorrect because if we substitute 3 into the equation, we get 3(3) - 9 = 9 - 9 = 0, which is also not equal to 18. Option D, 15, is incorrect because if we substitute 15 into the equation, we get
