1=3\left(-1\right)x+3-2x
Combine x and -2x to get -x.
1=-3x+3-2x
Multiply 3 and -1 to get -3.
1=-5x+3
Combine -3x and -2x to get -5x.
-5x+3=1
Swap sides so that all variable terms are on the left hand side.
-5x=1-3
Subtract 3 from both sides.
-5x=-2
Subtract 3 from 1 to get -2.
x=\frac{-2}{-5}
Divide both sides by -5.
x=\frac{2}{5}
Fraction \frac{-2}{-5} can be simplified to \frac{2}{5} by removing the negative sign from both the numerator and the denominator.
