2-7x+2\left(2x-1\right)=-14x+6x-35
Multiply both sides of the equation by 14, the least common multiple of 7,2,14.
2-7x+4x-2=-14x+6x-35
Use the distributive property to multiply 2 by 2x-1.
2-3x-2=-14x+6x-35
Combine -7x and 4x to get -3x.
-3x=-14x+6x-35
Subtract 2 from 2 to get 0.
-3x=-8x-35
Combine -14x and 6x to get -8x.
-3x+8x=-35
Add 8x to both sides.
5x=-35
Combine -3x and 8x to get 5x.
x=\frac{-35}{5}
Divide both sides by 5.
x=-7
Divide -35 by 5 to get -7.
