3+3x=-2(x+1)
the 2 is a negative
break it down

-3+3x=-2(x+1) First: I will get rid of the bracket:

-3+3x=-2x-2

Now, all the x goes to the left side, all the numbers without x to the right side:

3x+2x=-2+3

we add up"

5x=1

divide by 5:

-3 + 3x = -2(x + 1)

First, regroup your terms. / Your problem should look like: 
Second, expand. / Your problem should look like: 
Third, add 3 to both sides. / Your problem should look like: 
Fourth, simplify -2x - 2 + 3 to -2x + 1. / Your problem should look like: 
Fifth, add 2x to both sides. / Your problem should look like: 
Sixth, add 3x + 2x to get 5x. / Your problem should look like: 
Seventh, divide both sides by 5. / Your problem should look like: 

Answer as fraction: x =
