Given:

3/(2x - 1) + 4  = 6x/(2x - 1)

Solve for x.

Solution:

In order to solve for x, we simply need to multiply 2x-1 to both sides of the equation. In this way we'll be able to cancel out 3/(2x - 1) and 6x/(2x - 1).

3/(2x - 1) + 4  = 6x/(2x - 1)

(2x - 1) (3/(2x - 1) + 4 ) = (2x - 1) 6x/(2x - 1) 

3 + 4(2x - 1) = 6x

3 + 8x - 4 = 6x

-1 + 8x = 6x

Transpose 8x to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.

-1 = 6x - 8x

-1 = -2x

Divide both sides by -2 in order to cancel out -2x, leaving behind x.

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

x = ½

Final answer:

x = ½
