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

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

Answer as fraction: x =
(1)/(5)
Answer as decimal: x = 0.2

-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:


x= (1)/(5)
