2\left(x+5\right)-12\left(\frac{14-x}{2}-\frac{1}{4}\right)=2x-7
Multiply both sides of the equation by 12, the least common multiple of 6,2,4,12.
2x+10-12\left(\frac{14-x}{2}-\frac{1}{4}\right)=2x-7
Use the distributive property to multiply 2 by x+5.
2x+10-12\left(\frac{2\left(14-x\right)}{4}-\frac{1}{4}\right)=2x-7
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 2 and 4 is 4. Multiply \frac{14-x}{2} times \frac{2}{2}.
2x+10-12\times \frac{2\left(14-x\right)-1}{4}=2x-7
Since \frac{2\left(14-x\right)}{4} and \frac{1}{4} have the same denominator, subtract them by subtracting their numerators.
2x+10-12\times \frac{28-2x-1}{4}=2x-7
Do the multiplications in 2\left(14-x\right)-1.
2x+10-12\times \frac{27-2x}{4}=2x-7
Combine like terms in 28-2x-1.
2x+10-3\left(27-2x\right)=2x-7
Cancel out 4, the greatest common factor in 12 and 4.
2x+10-81+6x=2x-7
Use the distributive property to multiply -3 by 27-2x.
2x-71+6x=2x-7
Subtract 81 from 10 to get -71.
8x-71=2x-7
Combine 2x and 6x to get 8x.
8x-71-2x=-7
Subtract 2x from both sides.
6x-71=-7
Combine 8x and -2x to get 6x.
6x=-7+71
Add 71 to both sides.
6x=64
Add -7 and 71 to get 64.
x=\frac{64}{6}
Divide both sides by 6.
x=\frac{32}{3}
Reduce the fraction \frac{64}{6} to lowest terms by extracting and canceling out 2.
