4\left(5x-7\right)-6\left(1-x\right)=2\left(5-x\right)+3\left(3x-2\right)
Multiply both sides of the equation by 12, the least common multiple of 3,2,6,4.
20x-28-6\left(1-x\right)=2\left(5-x\right)+3\left(3x-2\right)
Use the distributive property to multiply 4 by 5x-7.
20x-28-6+6x=2\left(5-x\right)+3\left(3x-2\right)
Use the distributive property to multiply -6 by 1-x.
20x-34+6x=2\left(5-x\right)+3\left(3x-2\right)
Subtract 6 from -28 to get -34.
26x-34=2\left(5-x\right)+3\left(3x-2\right)
Combine 20x and 6x to get 26x.
26x-34=10-2x+3\left(3x-2\right)
Use the distributive property to multiply 2 by 5-x.
26x-34=10-2x+9x-6
Use the distributive property to multiply 3 by 3x-2.
26x-34=10+7x-6
Combine -2x and 9x to get 7x.
26x-34=4+7x
Subtract 6 from 10 to get 4.
26x-34-7x=4
Subtract 7x from both sides.
19x-34=4
Combine 26x and -7x to get 19x.
19x=4+34
Add 34 to both sides.
19x=38
Add 4 and 34 to get 38.
x=\frac{38}{19}
Divide both sides by 19.
x=2
Divide 38 by 19 to get 2.
