2\left(-x-\left(x-1\right)\right)=5\left(x-2\right)-6
Multiply both sides of the equation by 10, the least common multiple of 5,2.
2\left(-x-x-\left(-1\right)\right)=5\left(x-2\right)-6
To find the opposite of x-1, find the opposite of each term.
2\left(-x-x+1\right)=5\left(x-2\right)-6
The opposite of -1 is 1.
2\left(-x\right)-2x+2=5\left(x-2\right)-6
Use the distributive property to multiply 2 by -x-x+1.
2\left(-x\right)-2x+2=5x-10-6
Use the distributive property to multiply 5 by x-2.
2\left(-x\right)-2x+2=5x-16
Subtract 6 from -10 to get -16.
2\left(-x\right)-2x+2-5x=-16
Subtract 5x from both sides.
2\left(-x\right)-7x+2=-16
Combine -2x and -5x to get -7x.
2\left(-x\right)-7x=-16-2
Subtract 2 from both sides.
2\left(-x\right)-7x=-18
Subtract 2 from -16 to get -18.
-2x-7x=-18
Multiply 2 and -1 to get -2.
-9x=-18
Combine -2x and -7x to get -9x.
x=\frac{-18}{-9}
Divide both sides by -9.
x=2
Divide -18 by -9 to get 2.
