Let X be the number. Then your starting equation is:
3X + 19 = -X - 33
Can you solve it from here?

I will continue from here, then:
3X + 19 = -X - 33
3X = -X - 52 (subtract 19 from both sides)
4X = -52 (add X to both sides)
X = -13 (divide both sides by 4)
I hope this helps.

where did the 4 come from if it was 3 before you added X to both sides?
