3x-3-2\left(2x+1\right)-x=6
Use the distributive property to multiply 3 by x-1.
3x-3-4x-2-x=6
Use the distributive property to multiply -2 by 2x+1.
-x-3-2-x=6
Combine 3x and -4x to get -x.
-x-5-x=6
Subtract 2 from -3 to get -5.
-x-x=6+5
Add 5 to both sides.
-x-x=11
Add 6 and 5 to get 11.
-2x=11
Combine -x and -x to get -2x.
x=\frac{11}{-2}
Divide both sides by -2.
x=-\frac{11}{2}
Fraction \frac{11}{-2} can be rewritten as -\frac{11}{2} by extracting the negative sign.
