Solving Compound Inequalities Transform each compound inequality into two linear inequalities and solve them independently by isolating the variable. It does not matter on which side we choose to isolate the variable because the symmetric property134 states that \(4 = y\) is equivalent to \(y = 4\). Solve and graph the solution set: \(5x+7<22\). A linear equation may have one or two variables in it, where each variable is raised to the power of 1. If \(A3\). Dividing by \(0\) is undefined and multiplying both sides by \(0\) results in the equation \(0 = 0\). There is no upper end to the solution to this inequality. 16pt 6. Shade to the right of \(3\), and put a bracket at \(3\). Our free graphing linear inequalities worksheets are a good place to begin practice. are a great way for students to practice topics or show proficiency. The procedure of the problem is also shown step by step. When no sign precedes the term, it is understood to be positive. To illustrate the problem, consider the true statement \(10 > 5\) and divide both sides by \(5\). \(\begin{array} { l } { 10 \color{OliveGreen}{>}\color{Black}{ - 5} } \\ { \frac { 10 } { \color{Cerulean}{- 5} } \color{Black}{<} \frac { - 5 } { \color{Cerulean}{- 5} } } \quad \color{Cerulean}{Reverse\: the\: inequality.} \(\begin{aligned} 3 x - 12 & = 0 \\ 3 ( \color{Cerulean}{4}\color{Black}{ )} - 12 & = 0 \\ 12 - 12 & = 0 \\ 0 & = 0 \:\:\color{Cerulean}{} \end{aligned}\), Alternatively, when an equation is equal to a constant, we may verify a solution by substituting the value in for the variable and showing that the result is equal to that constant. Pre-made digital activities. Usually, this translation to mathematical statements is the difficult step in the process. This step not only makes our work more readable, but also forces us to think about what we are looking for. Step 4: Solve the resulting algebraic equation.
