Again, solve inequalities the same way you solve equations…use the OPPOSITE operation. Remember that when you are MULTIPLYING or DIVIDING by a NEGATIVE COEFFICIENT that causes your inequality sign to change. ***Always check your answers (at least mentally) to make sure they actually work!

i.e.Solve x > 8 5 ***Because this problem involves division, you will solve it by MULTIPLYING by the RECIPROCAL of the COEFFICIENT….5 5 ● x > 8 ● 5 5 x > 40

i.e.Solve -3c ≥ 2 This problem involves multiplication, so we will DIVIDE by the coefficient to get rid of the -3…and it is a NEGATIVE coefficient, so the ≥ will switch to ≤. -3c ≥ 2 -3 c ≤ -2/3 **Check your answer to make sure it works!
