Add 2 to each side; what do you get?

the second one
Note that , and we're given . Therefore it follows that . Alternatively, you can multiply both sides by 3x-2.
This solution can also be solved with another method such as e.g :- x/4 - 3x/2 = -1/2 4(x/4 - 3x/2) = 4(-1/2) x - 2(3x) = 2(-1) x - 6x = -2 -5x = -2 x = -2/-5 x = 2/5 (0.4)

@emakarov, . Since is one-to-one (assuming ), it follows that (by equating denominators).
