State the rules for working with inequalities.

Answer to Problem 19RCC
if
If
Explanation of Solution
Given information:
State the rules for working with inequalities.
Calculation:
The rules are same for inequalities as for equalities. The first rule involves adding or subtracting a value from both sides of an inequality. If says that value of inequality remains same.
If
If a constant is multiplied both sides of an equality, if the constant is positive then the direction of inequality is unchanged. if the constant is negative then the direction of inequality is changed.
