4x - 2x - 5 = 4 + 6x + 3

Goal is to isolate x on one side to be able to solve.

2x - 5 = 7 + 6x

Combine like terms.

2x - 5 + 5 = 7 + 6x + 5

Add 5 to each side.

2x = 12 + 6x

Subtract 6x from each side.

-4x = 12

Then, divide both sides by -4

x = -3

CHECK your solution by plugging back into the original equation.
