add a to both sides
x=-x+2a +4......add x to both sides
2x = 2a + 4......divide by 2
x = a + 2

Add x from both sides:
2x-a=a+4
Add a from both sides:
2x=2a+4
Divide 2 from both sides:
x=a+2
I hope this is the answer you are looking for!

x - a = -x + a + 4
x + x = a +a + 4
2x = 2a + 4
x = a +2

x-a=-x+a+4
add x to both sides
2x-a=a+4
add a to both sides
2x=2a+4
take 2 as common
2(x)=2(a+2)
divide both sides by 2
u will get ur answer as x=a+2

u have to:
add a to each side: x=-x+2a+4
then add x to both sides: 2x=2a+4
then divide by two: x=a+2
