WebThe methods used to solve linear inequalities are similar to those used to solve linear equations. The only difference occurs when there is a multiplication or a division that involves a minus sign. For example, we know that $8>6$. If both sides of the inequality are divided by $-\text{2}$, then we get $-4>-3$, which is not true. WebA linear inequality is one such that if we replaced the inequality with the equals relation, then we would have a linear equation. Solving linear inequalities is very much like solving linear equations, with one important difference. When you multiply or divide both sides of an inequality by a negative number, the direction of the inequality is ... WebExample 5 is a formula giving interest (I) earned for a period of D days when the principal (p) and the yearly rate (r) are known. Find the yearly rate when the amount of interest, the principal, and the number of days are all known. Solution. The problem requires solving for r..
