3-x-1=x-4
Variable x cannot be equal to 4 since division by zero is not defined. Multiply both sides of the equation by x-4, the least common multiple of x-4,4-x.
2-x=x-4
Subtract 1 from 3 to get 2.
2-x-x=-4
Subtract x from both sides.
2-2x=-4
Combine -x and -x to get -2x.
-2x=-4-2
Subtract 2 from both sides.
-2x=-6
Subtract 2 from -4 to get -6.
x=\frac{-6}{-2}
Divide both sides by -2.
x=3
Divide -6 by -2 to get 3.
