We simplify the equation to the form, which is simple to understand
4x+8-2x=20

We move all terms containing x to the left and all other terms to the right.
+4x-2x=+20-8

We simplify left and right side of the equation.
+2x=+12

We divide both sides of the equation by 2 to get x.
x=6

4x+8=2x+7+2x-20

Combine like terms: 4x+8=4x-13
Subtract 8 from each side: 4x=4x-21
Subtract 4x from each side: 0= -21
There are no solutions to this equation.
