CHAPTER 2 Solving Equations and Inequalities 84 University of Houston Department of Mathematics Additional Example 2: Solution: Additional Example 3: Solution: We first multiply both sides of the equation by 12 to clear the equation of fractions. As indicated, you should expect $x=0$ to solve the original inequality and that $x=5$ should not. We use the left parenthesis symbol, (, to show that the endpoint of the inequality is not included. Developing techniques for solving various algebraic equations is one of our main goals in algebra. Doing math equations is a great way to keep your mind sharp and . \(\begin{array} { c } { \frac { 1 } { 2 } x - 2 \geq \frac { 1 } { 2 } \left( \frac { 7 } { 4 } x - 9 \right) + 1 } \\ { \frac { 1 } { 2 } x - 2 \geq \frac { 7 } { 8 } x - \frac { 9 } { 2 } + 1 } \\ { \frac { 1 } { 2 } x - \frac { 7 } { 8 } x \geq - \frac { 7 } { 2 } + 2 } \\ { - \frac { 3 } { 8 } x \geq - \frac { 3 } { 2 } } \\ { \left( \color{Cerulean}{- \frac { 8 } { 3 }} \right) \left(\color{Black}{ - \frac { 3 } { 8 } x} \right) \leq \left( \color{Cerulean}{- \frac { 8 } { 3 }} \right) \left( \color{Black}{-} \frac { 3 } { 2 } \right) \quad \color{Cerulean} { Reverse\: the\: inequality. } Algebra 2 Linear Equations & Inequalities. When solving linear equations, the goal is to determine what value, if any, will produce a true statement when substituted in the original equation. x\[~?;NJd`vd$87_Q]$18.D)w?=[!>{x|_~a5UwF]/?9d+s8$Paa2A)0ihAf;{*k JyGj2%0YS+@~5~Swkl\KBN*$%|.>o.
