5x−8=3x+3 whats the x?

$$5x-8=3x+3 \quad | \quad-3x\\\\ \underbrace{5x-3x}_{2x}-8 = \underbrace{3x-3x}_{0}+3\\\\ 2x-8=3\quad | \quad +8\\\\ 2x\underbrace{-8+8}_{0} =3+8\\\\ 2x=11\quad | \quad:2\\\\ {\not{2}x\over \not{2}} = {11 \over 2}\\\\ x={11 \over 2}\\\\ x=5.5$$

Technically you do not transer them from one side to the other.

you add or subtract or whatever from BOTH sides.

Maybe this was a trick question Rosala.

Thanks Heueka,

It probably was the graphical answer that was desired. I didn't even think of that.
