-x-16x=2\left(x-12\right)-12+x
Multiply both sides of the equation by 8, the least common multiple of 8,4,2.
-x-16x=2x-24-12+x
Use the distributive property to multiply 2 by x-12.
-x-16x=2x-36+x
Subtract 12 from -24 to get -36.
-x-16x=3x-36
Combine 2x and x to get 3x.
-x-16x-3x=-36
Subtract 3x from both sides.
-x-19x=-36
Combine -16x and -3x to get -19x.
-20x=-36
Combine -x and -19x to get -20x.
x=\frac{-36}{-20}
Divide both sides by -20.
x=\frac{9}{5}
Reduce the fraction \frac{-36}{-20} to lowest terms by extracting and canceling out -4.
