Solve compound inequalities

To solve for a variable, use inverse operations to undo the operations in the inequality. Be sure to do the same operation to all parts of the inequality.


Solve for f.

-5 < f + 13 ≤ 5

-5 -13 < f + 13 -13 ≤ 5 -13

  Subtract 13 from each part of the inequality

-18 < f ≤ -8
  Simplify


Solve for e

3 > e + 4 ≥ 4


7 > e ≥ 0
-1 > e ≥ 8
-1 > e ≥ 0
7 > e ≥ 8
