Explanation:

To solve this problem

collect like terms

x-2x = -4

-x =-4

divide both sides of the equation by -

-x /- =-4

x=4

Combine like terms by subtracting x from both sides.
x + 4 = 2x
4 = 2x - x
4 = x

(On one side, x-x cancelled out, and on the other side, the 2x-x works like normal subtraction so you are left with x. Therefore x is 4)
