1-x-2x=-3
Subtract 2x from both sides.
1-3x=-3
Combine -x and -2x to get -3x.
-3x=-3-1
Subtract 1 from both sides.
-3x=-4
Subtract 1 from -3 to get -4.
x=\frac{-4}{-3}
Divide both sides by -3.
x=\frac{4}{3}
Fraction \frac{-4}{-3} can be simplified to \frac{4}{3} by removing the negative sign from both the numerator and the denominator.
