Solve for f
f<3

2-f>-1
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
-f>-1-2
Subtract 2 from both sides.
-f>-3
Subtract 2 from -1 to get -3.
f<\frac{-3}{-1}
Divide both sides by -1. Since -1 is negative, the inequality direction is changed.
f<3
Fraction \frac{-3}{-1} can be simplified to 3 by removing the negative sign from both the numerator and the denominator.
