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.

**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$$

I like your \underbrace{}_

Heureka, I do not think that I have seen you use that before.

Another for me to try and remember and make use of. Thank you.
