a)-9x-10%3C=-46add 10 to both sides of equation
:
-9x%3C=-36 now divide both sides by -9 remembering that dividing by a
:
negative reverses the inequality sign.

:
b)-6%3C=3%28x-1%29%3C12 distribute the middle term 3(x-1)=3x-3
:
-6%3C=3x-3%3C12now add 3 to all terms
:
-3%3C=3x%3C15now divide all terms by 3 to isolate the x
:
highlight%28-1%3C=x%3C5%29
