Excuse me what is 6=2(y+2) ?

Distribute the 2 through the parentheses

on the right side of the equation.

2(y) is 2y and 2(2) is 4.

So the problem now reads 6 = 2y + 4.

Now we can subtract 4 from both

sides of the equation to get 2 = 2y.  

Now divide both sides of the

equation by 2 and 1 = y.
