2\left(7-3x-2x\right)-3=3-\left(1-2x\right)
Add 1 and 6 to get 7.
2\left(7-5x\right)-3=3-\left(1-2x\right)
Combine -3x and -2x to get -5x.
14-10x-3=3-\left(1-2x\right)
Use the distributive property to multiply 2 by 7-5x.
11-10x=3-\left(1-2x\right)
Subtract 3 from 14 to get 11.
11-10x=3-1-\left(-2x\right)
To find the opposite of 1-2x, find the opposite of each term.
11-10x=3-1+2x
The opposite of -2x is 2x.
11-10x=2+2x
Subtract 1 from 3 to get 2.
11-10x-2x=2
Subtract 2x from both sides.
11-12x=2
Combine -10x and -2x to get -12x.
-12x=2-11
Subtract 11 from both sides.
-12x=-9
Subtract 11 from 2 to get -9.
x=\frac{-9}{-12}
Divide both sides by -12.
x=\frac{3}{4}
Reduce the fraction \frac{-9}{-12} to lowest terms by extracting and canceling out -3.
