Starting with the expression:


3x-2x+4=2+x+2

Substract 2x from 3x on the left hand side of the equation, since those are like terms:


\Rightarrow x+4=2+x+2

Use the commutative property to change the order of the terms on the right hand side of the equation:


\Rightarrow x+4=x+2+2

Add 2+2 on the right hand side:


x+4=x+4

Since both expressions on the right and on the left are the same, any value of x will make the equation true.

Therefore, all numbers are a solution for this equation.
