2x - y = 8
I don't need the exact value of x. I need the formula
I already answered one of these types of questions, and the answer should look something like this:
Solve for c: p = a + b + c
Answer: c = a + b - p

x = (8+y)/2 after you add y on both sides and divide by 2 on both sides
This simplifies to x=y/2+4

Yes, so just move everything else to the other side.
2x=8+y
x=(8/2)+(y/2)
Simplified....x=(1/2)y+4

2x - y = 8
2x = 8 + y
x = (8+y) / 2 = 4 + (y/2)

okay its pretty simple
2x-y=8, you want to get the variable by itself, in this case x
2x-y=8
+y +y
______
2x=8+y
-- ----- (fraction bar)
2 2
x=8/2+y/2
x=4+1/2y

2x-y=8
2x=y+8
2x/2=y+8/2
