Solving inequalities. mc-TY-inequalities-2009-1. Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤. To ‘solve’ an inequality means to find a range, or ranges, of values that an unknown x can take and still satisfy the inequality. In this unit inequalities are solved by using algebra and by using graphs.

Definition 8.1. Two inequalities are equivalent if they have the same solution set. Operations that Produce Equivalent Inequalities. Add or Subtract the same value on both sides of the inequality. Multiply or Divide by the same positive value on both sides of the inequality. Multiply or Divide by the same negative value on both sides of the ...

There are many rules for studying inequalities which are derivable from the axioms. The reader will be asked to prove many of them in the exercises. These are not axioms. Theorem 1. Let a, b, c, and d be real numbers. Then E1: (Inequalities add) If a < b and c < d, then a+c < b+d. E2: (Positive inequalities multiply) If 0 < a < b and 0 < c < d,

Example 2x+ 1 3 is an inequality. The solution of an inequality is the set of all numbers which satisfy the inequality. This set may have in nitely many numbers and may be represented by an interval or a number of intervals on the real line. Example The solution to the inequality 2x+ 1 3 is the set of all x 1. 3 2.5 2 1.5 1 0.5 Ð 0.5 Ð 1 Ð 1 ...

However inequalities are more difficult than equations because there are more restrictions on the sort of operations that are valid. The first, however, is very easy: if. x + z < y + z . That is, you can add anything to both sides of the inequality. The same goes for subtraction. Already with multiplication you have to be more careful: if x < y ...
