<PRE><B>Question 168668</B>
(3x-1)/2x = 40

We first multiply both sides by 2x to remove the fraction on the left side.
Here, 2x represents the LCD.

(3x-1)/2x times 2x = 3x - 1

40 times 2x = 80x

We now have a linear equation:

3x - 1 = 80x

Solve for x.

-1 = 80x - 3x

-1 = 77x

Divide both sides by 77 to find x.

-1/77 = x

I hope this helps.</PRE>
