x over 3x+2-2=5

x over 3x+2-2=5  .... kazza1969, the way you have this written, we have :

x/(3x) + 2 - 2  = 5  simplify

x/(3x)  = 5     multiply both sides by 3x

x = 15x      subtract 15x  from both sides

-14x = 0     which implies that x = 0.......but, this means one of the terms in the original problem  - x/(3x)  -   would result in 0/0.......and that's an indeterminate quantity

I have a feeling that you meant this:

x /(3x + 2) - 2 = 5    add 2 to both sides

x/(3x + 2)  = 7    multiply both sides by 3x + 2

x = 7(3x + 2)    simplify

x = 21x + 14    subtract 21z from both sides

-20x = 14     divide by -20 on each side

x = -14/20  = -7/10   Jun 1, 2015
