2x + a = 4

2x = 4 - a

x = (4 - a) / 2

You can simplify this further to:

x = 2 - a/2

2x+a=4

2x = 4 - a

x = (4 - a)/2

which also = 

2 - (a/2)

x: 2x + a =4

since we are solving for x we need to get it alone so minus a

2x= 4 - a

now divide everything by 2 to get x alone

`(2x) / 2 = 4 / 2 - a/2`

`x = 2 - a/2`

2x+a=4

Move the variable you need on one side

2x=4-a

then divide

x=(4-a)/2
