50-x=6\left(2x-1\right)
Variable x cannot be equal to \frac{1}{2} since division by zero is not defined. Multiply both sides of the equation by 2x-1.
50-x=12x-6
Use the distributive property to multiply 6 by 2x-1.
50-x-12x=-6
Subtract 12x from both sides.
50-13x=-6
Combine -x and -12x to get -13x.
-13x=-6-50
Subtract 50 from both sides.
-13x=-56
Subtract 50 from -6 to get -56.
x=\frac{-56}{-13}
Divide both sides by -13.
x=\frac{56}{13}
Fraction \frac{-56}{-13} can be simplified to \frac{56}{13} by removing the negative sign from both the numerator and the denominator.
