18\left(\frac{2x-1}{3}-\frac{1-2x}{2}\right)=2\left(2-x\right)-6+6x
Multiply both sides of the equation by 6, the least common multiple of 3,2.
18\left(\frac{2\left(2x-1\right)}{6}-\frac{3\left(1-2x\right)}{6}\right)=2\left(2-x\right)-6+6x
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-1}{3} times \frac{2}{2}. Multiply \frac{1-2x}{2} times \frac{3}{3}.
18\times \frac{2\left(2x-1\right)-3\left(1-2x\right)}{6}=2\left(2-x\right)-6+6x
Since \frac{2\left(2x-1\right)}{6} and \frac{3\left(1-2x\right)}{6} have the same denominator, subtract them by subtracting their numerators.
18\times \frac{4x-2-3+6x}{6}=2\left(2-x\right)-6+6x
Do the multiplications in 2\left(2x-1\right)-3\left(1-2x\right).
18\times \frac{10x-5}{6}=2\left(2-x\right)-6+6x
Combine like terms in 4x-2-3+6x.
3\left(10x-5\right)=2\left(2-x\right)-6+6x
Cancel out 6, the greatest common factor in 18 and 6.
30x-15=2\left(2-x\right)-6+6x
Use the distributive property to multiply 3 by 10x-5.
30x-15=4-2x-6+6x
Use the distributive property to multiply 2 by 2-x.
30x-15=-2-2x+6x
Subtract 6 from 4 to get -2.
30x-15=-2+4x
Combine -2x and 6x to get 4x.
30x-15-4x=-2
Subtract 4x from both sides.
26x-15=-2
Combine 30x and -4x to get 26x.
26x=-2+15
Add 15 to both sides.
26x=13
Add -2 and 15 to get 13.
x=\frac{13}{26}
Divide both sides by 26.
x=\frac{1}{2}
Reduce the fraction \frac{13}{26} to lowest terms by extracting and canceling out 13.
