-1-x=-6+2x
Use the distributive property to multiply -2 by 3-x.
-1-x-2x=-6
Subtract 2x from both sides.
-1-3x=-6
Combine -x and -2x to get -3x.
-3x=-6+1
Add 1 to both sides.
-3x=-5
Add -6 and 1 to get -5.
x=\frac{-5}{-3}
Divide both sides by -3.
x=\frac{5}{3}
Fraction \frac{-5}{-3} can be simplified to \frac{5}{3} by removing the negative sign from both the numerator and the denominator.
