30\left(\frac{x}{2}+\frac{1}{6}\right)-2=6x-12\left(1-\frac{x}{3}\right)
Multiply both sides of the equation by 6, the least common multiple of 2,6,3.
30\left(\frac{3x}{6}+\frac{1}{6}\right)-2=6x-12\left(1-\frac{x}{3}\right)
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 2 and 6 is 6. Multiply \frac{x}{2} times \frac{3}{3}.
30\times \frac{3x+1}{6}-2=6x-12\left(1-\frac{x}{3}\right)
Since \frac{3x}{6} and \frac{1}{6} have the same denominator, add them by adding their numerators.
5\left(3x+1\right)-2=6x-12\left(1-\frac{x}{3}\right)
Cancel out 6, the greatest common factor in 30 and 6.
15x+5-2=6x-12\left(1-\frac{x}{3}\right)
Use the distributive property to multiply 5 by 3x+1.
15x+3=6x-12\left(1-\frac{x}{3}\right)
Subtract 2 from 5 to get 3.
15x+3+12\left(1-\frac{x}{3}\right)=6x
Add 12\left(1-\frac{x}{3}\right) to both sides.
15x+3+12+12\left(-\frac{x}{3}\right)=6x
Use the distributive property to multiply 12 by 1-\frac{x}{3}.
15x+3+12-4x=6x
Cancel out 3, the greatest common factor in 12 and 3.
15x+15-4x=6x
Add 3 and 12 to get 15.
11x+15=6x
Combine 15x and -4x to get 11x.
11x+15-6x=0
Subtract 6x from both sides.
5x+15=0
Combine 11x and -6x to get 5x.
5x=-15
Subtract 15 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-15}{5}
Divide both sides by 5.
x=-3
Divide -15 by 5 to get -3.
