12\left(\frac{2\left(2x-1\right)}{3}+\frac{3\left(2x-1\right)}{4}\right)-10\left(2x-1\right)=0
Multiply both sides of the equation by 12, the least common multiple of 3,4,6.
12\left(\frac{4x-2}{3}+\frac{3\left(2x-1\right)}{4}\right)-10\left(2x-1\right)=0
Use the distributive property to multiply 2 by 2x-1.
12\left(\frac{4x-2}{3}+\frac{6x-3}{4}\right)-10\left(2x-1\right)=0
Use the distributive property to multiply 3 by 2x-1.
12\left(\frac{4\left(4x-2\right)}{12}+\frac{3\left(6x-3\right)}{12}\right)-10\left(2x-1\right)=0
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 3 and 4 is 12. Multiply \frac{4x-2}{3} times \frac{4}{4}. Multiply \frac{6x-3}{4} times \frac{3}{3}.
12\times \frac{4\left(4x-2\right)+3\left(6x-3\right)}{12}-10\left(2x-1\right)=0
Since \frac{4\left(4x-2\right)}{12} and \frac{3\left(6x-3\right)}{12} have the same denominator, add them by adding their numerators.
12\times \frac{16x-8+18x-9}{12}-10\left(2x-1\right)=0
Do the multiplications in 4\left(4x-2\right)+3\left(6x-3\right).
12\times \frac{34x-17}{12}-10\left(2x-1\right)=0
Combine like terms in 16x-8+18x-9.
\frac{12\left(34x-17\right)}{12}-10\left(2x-1\right)=0
Express 12\times \frac{34x-17}{12} as a single fraction.
34x-17-10\left(2x-1\right)=0
Cancel out 12 and 12.
34x-17-20x+10=0
Use the distributive property to multiply -10 by 2x-1.
14x-17+10=0
Combine 34x and -20x to get 14x.
14x-7=0
Add -17 and 10 to get -7.
14x=7
Add 7 to both sides. Anything plus zero gives itself.
x=\frac{7}{14}
Divide both sides by 14.
x=\frac{1}{2}
Reduce the fraction \frac{7}{14} to lowest terms by extracting and canceling out 7.
