3x%2B3=-2x-12 Start with the given equation.


3x=-2x-12-3 Subtract 3 from both sides.


3x%2B2x=-12-3 Add 2x to both sides.


5x=-12-3 Combine like terms on the left side.


5x=-15 Combine like terms on the right side.


x=%28-15%29%2F%285%29 Divide both sides by 5 to isolate x.


x=-3 Reduce.

3x+3=-2x-12

Let's get all the x terms on the left side, and the numbers on the right.

Add 2x to both sides:
3x+3+2x=-2x-12+2x
5x+3 = -12

Subtract 3 from both sides:
5x+3-3 = -12-3
5x = -15

Divide both sides by 5:
5x/5 = -15/5
x = -3

So x= -3.

Okay, from
3x + 3 = -2x - 12
we want to get all the x's on one side and all the numbers on the other...
so let's add 2x to both sides first and get
5x + 3 = -12
now subtract 3...
5x = -15
now divide by five...
x = -3
