No, it is not a direct variation.
8x-4
14
It can be simplified to: 2x+33
it equals 13X.
2x = 2x + 0 Hence the constant term is 0 (zero)
No, it is not a direct variation.
8x-4
3x + 2x - 8x + 2x = -x
x=1
It is 2x+(-2x) = 0
4
-2x + 6 + 22 = -2x + 28
14
6 + 2x + 5 = 11 + 2x
2x
It can be simplified to: 2x+33
