A linear inequality is similar to a linear equation, but the equal sign is replaced with an inequality symbol. A solution of a linear inequality is any ordered pair that makes the inequality true.. Identifying Solutions of Inequalities. Tell whether the ordered pair is a solution of the inequality. Example 1 : (7, 3) ; y < x - …

Instead of using an Se hela listan på quickmath.com   Solving inequalities is the same as solving equations. There are only 2 things you need to know…   1.) If you multiply or divide by a negative number you must switch the sign. -7x < 21 -7 -7 x > -3 Solving Inequalities. Inequalities are not always presented to us in a straight forward way.

Free inequality calculator - solve linear, quadratic and absolute value inequalities step-by-step This website uses cookies to ensure you get the best experience. By using this website, you agree to our Cookie Policy. The solutions for inequalities generally involve the same basic rules as equations. There is one exception, which we will soon discover. The first rule, however, is similar to that used in solving equations. If the same quantity is added to each side of an inequality, the results are unequal in the same order. To solve an inequality, we can: Add the same number to both sides.
