2(x + 2) = 4
x + 2 = 4/2
x + 2 = 2
x = 2 - 2
x = 0
checking:
2(x + 2) = 4
2(0 + 2) = 4?
2 + 2 = 4
4 = 4

multiple 2 times the stuff inside ( )
2x + 4 = 4
subtract 4 from both sides
2x = 0
divide zero by 2
x = 0

First multiply to open pretenses we get
2x+4=4
subtract by (4) both sides to get
2x+4-4=4-4
2x=0
divide both sides by 2
x=0
