When you have the same variable on both sides of the equation you want to start by isolating the variable (in this case x) on one side.

I would start by adding 12 to each side

3x-12+12=-2x+83+12

-12+12 cancels out to zero and you add 12 to 83

This leaves you with 3x=-2x+95

Next add 2x to each side

3x+2x=-2x+2x+95

-2x+2x cancels out to zero

This leaves you with 5x=95

Now divide each side by 5

5x/5=95/5

5/5=1 which leaves you with 1x or just x if you prefer. 95/5=19

Therefore you answer is x=19

Hope this helps.
