(1/x) - 1 - (3/x) + 2 = (1/4)
We simplify as much as we can to get:
(-2/x) + 1 = (1/4)
We isolate the 'x' on one side to get:
-2/x = -3/4
We multiply by 'x' to get out of the fraction:
-2 = (-3x/4)
Multiply by 4 to get rid of all the fractions completely:
-8 = -3x
Divide by -3 to solve
8/3 = x
We plug back in to check and it comes out correct.
