x+3-2x<1
Subtract 2x from both sides.
-x+3<1
Combine x and -2x to get -x.
-x<1-3
Subtract 3 from both sides.
-x<-2
Subtract 3 from 1 to get -2.
x>\frac{-2}{-1}
Divide both sides by -1. Since -1 is negative, the inequality direction is changed.
x>2
Fraction \frac{-2}{-1} can be simplified to 2 by removing the negative sign from both the numerator and the denominator.
