Question 168668: 3x-1/2x=40
Answer by midwood_trail(310)   (Show Source):
You can put this solution on YOUR website! (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.
