Same rules as for solving equations.
If x – 2 = 3, add 2 to both sides, x = 5
If x – 2 > 5, add 2 to both sides, x > 5
If – 4 > a + 7, subtract 7 from both sides, - 11 > a or a > - 11

South American manatees can weigh up to 1300 pounds.
If one of the manatees weighs 968 pounds, up to how much weight might this manatee gain?
Using w to represent the weight gained, write an inequality and solve it.
