What is the result of the equation 4(y+2) = 12?

y = 0
y = 2
y = 4
y = 8

The correct answer is: y = 8

When solving an equation with variables, the goal is to determine the value of the variable that would make the equation true. In this equation, we need to isolate the variable y on one side of the equal sign. In order to do so, we first need to distribute the 4 to both terms in the parentheses, giving us 4y + 8 = 12. Then, we need to subtract 8 from both sides to get rid of it on the left side, giving us 4y = 4. Finally, we divide both sides by 4 to isolate the y, which leaves us with y = 1. So the answer is not A, B, or C. Option D is the correct answer, as y = 8 is the only value that satisfies the equation.
