1. You solve inequalities in the same manner as you solve equations with a few exceptions:
a) If you mulitply/divide both sides of an inequality by a negative number you have to change the < sign into a > sign, and the > sign into a < sign.
to #g: Do you mean:
? Mulitply by 2, subtract 3, done!
to #j: Expand the bracket, add 6, divide by 2
to #m: subtract 1, subtract 2x,
and the last one is intirely for you
