You're joking, right?

Are you trying to solve for y, or show that left side = right side?

8y - 3(4 - 2y) = 6(y + 1)
8y - (12 - 6y) = 6y + 6 <- expand into brackets
8y - 12 + 6y = 6y + 6
14y - 12 = 6y + 6
14y - 6y = 6 + 12 <- bring like terms togethor
8y = 18
8y/8 = 18/8
y = 2.25

Doesn't seem like the answer you were looking for.

Here's a hint:

After expanding the function, it looks like this:

8y - 3(4 - 2y) = 6(y + 1) <=> 8y - 12 + 6y = 6y + 6

<=> equals equivalence, or the left equation is the same as the right equation. Then its simple algebra isolating the y on one side of the equation and solving for it.

Lol what math is this?

You just use the distributive property for the numbers in the parentheses. Then add and subtract the numbers on the other side.
