3x-2/3x=4/3

7/3x = 4/3

x = (4/3) / (7/3)

x = (4/3) * (3/7)

x = 12/21 = 4/7

I think this problem is really

(3x - 2) / 3x = 4 / 3

[cross multiply]

3(3x - 2) = 4 * 3x

9x - 6 = 12x

9x -6 + 6 = 12x +'6

9x = 12x + 6

9x - 12x = 12x + 6 - 12x

-3x = 6

x = -2

3x - 2/3x = 2 1/3x

2 1/3 = 7/3

Thanks Jake, but the ans. to this problem is x=4/7, so the set up is... 3x-2/3x-4/3.
