8x+40

I believe when X-3=5 the answer would be 8 because 5+3=8.
you just equal that equation to 0, then you solve for x 5x-8=0 5x=8 x=8/5
2 x 2 x 2 = 8 2 x 2 x 2 x 5 = 40
If you mean: x+8-x+9 when x = 5 Then it is: 5+8-5+9 = 17
Are you trying to find x? If so, get all x's to one side, 32=8x-8, then get x alone... 40= 8x then divide by 8... 5=x So at x=5, 4x+32=12x-8
