how would i do 2x+12=5x+8-x?????????

2x+12=5x+8-x

This seems to be a continuing question.

The idea is to gather the x's on one side, and the constants on the other.
Subtract 2x from both sides.
subtract 8 from both sides.
You ought to have numbers on one side, and x's on the other. Simplify both sides by combining.
I get
4=2x
divide both sides by 2. You have solved for x.
