D) x = 1

Question

Quizplus · Accepted Answer

To start solving this equation, we need to use the distributive property of multiplication over addition:

3(x + 2) = 12

3x + 6 = 12

Next, we want to isolate the variable on one side of the equation. To do this, we'll subtract 6 from both sides:

3x + 6 - 6 = 12 - 6

3x = 6

Finally, we'll solve for x by dividing both sides by 3:

3x/3 = 6/3

x = 2

Therefore, the solution to the equation is x = 2, so the best choice is C.
