12\left(\frac{x}{2}+\frac{1}{3}\right)=18\left(\frac{2x}{3}-\frac{1}{2}\right)+6
Multiply both sides of the equation by 6, the least common multiple of 2,3.
12\left(\frac{3x}{6}+\frac{2}{6}\right)=18\left(\frac{2x}{3}-\frac{1}{2}\right)+6
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 2 and 3 is 6. Multiply \frac{x}{2} times \frac{3}{3}. Multiply \frac{1}{3} times \frac{2}{2}.
12\times \frac{3x+2}{6}=18\left(\frac{2x}{3}-\frac{1}{2}\right)+6
Since \frac{3x}{6} and \frac{2}{6} have the same denominator, add them by adding their numerators.
2\left(3x+2\right)=18\left(\frac{2x}{3}-\frac{1}{2}\right)+6
Cancel out 6, the greatest common factor in 12 and 6.
6x+4=18\left(\frac{2x}{3}-\frac{1}{2}\right)+6
Use the distributive property to multiply 2 by 3x+2.
6x+4=18\left(\frac{2\times 2x}{6}-\frac{3}{6}\right)+6
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 3 and 2 is 6. Multiply \frac{2x}{3} times \frac{2}{2}. Multiply \frac{1}{2} times \frac{3}{3}.
6x+4=18\times \frac{2\times 2x-3}{6}+6
Since \frac{2\times 2x}{6} and \frac{3}{6} have the same denominator, subtract them by subtracting their numerators.
6x+4=18\times \frac{4x-3}{6}+6
Do the multiplications in 2\times 2x-3.
6x+4=3\left(4x-3\right)+6
Cancel out 6, the greatest common factor in 18 and 6.
6x+4=12x-9+6
Use the distributive property to multiply 3 by 4x-3.
6x+4=12x-3
Add -9 and 6 to get -3.
6x+4-12x=-3
Subtract 12x from both sides.
-6x+4=-3
Combine 6x and -12x to get -6x.
-6x=-3-4
Subtract 4 from both sides.
-6x=-7
Subtract 4 from -3 to get -7.
x=\frac{-7}{-6}
Divide both sides by -6.
x=\frac{7}{6}
Fraction \frac{-7}{-6} can be simplified to \frac{7}{6} by removing the negative sign from both the numerator and the denominator.
