6\left(x-2\right)-2\left(x+1\right)+28=12x+9
Multiply both sides of the equation by 12, the least common multiple of 2,6,3,4.
6x-12-2\left(x+1\right)+28=12x+9
Use the distributive property to multiply 6 by x-2.
6x-12-2x-2+28=12x+9
Use the distributive property to multiply -2 by x+1.
4x-12-2+28=12x+9
Combine 6x and -2x to get 4x.
4x-14+28=12x+9
Subtract 2 from -12 to get -14.
4x+14=12x+9
Add -14 and 28 to get 14.
4x+14-12x=9
Subtract 12x from both sides.
-8x+14=9
Combine 4x and -12x to get -8x.
-8x=9-14
Subtract 14 from both sides.
-8x=-5
Subtract 14 from 9 to get -5.
x=\frac{-5}{-8}
Divide both sides by -8.
x=\frac{5}{8}
Fraction \frac{-5}{-8} can be simplified to \frac{5}{8} by removing the negative sign from both the numerator and the denominator.
