Using inequalities to solve problems Get 3 of 4 questions to level up! The solutions are presented graphically on a number line or using interval notation or both. Solve: \(\frac { 5 } { 3 } x + 2 = - 8\). Because the number three itself is not a solution, we put an open parenthesis at three. The answer to the first problem takes you to a new problem, the answer to that problem takes you to another problem, and so on until the last problem's answer returns you to the original question. Use the properties of equality to solve basic linear equations. Recall that when evaluating expressions, it is a good practice to first replace all variables with parentheses, and then substitute the appropriate values. \(\begin{aligned} 2 ( n + 8 ) - 6 & = 5 \\ 2 n + 16 - 6 & = 5 \\ 2 n + 10 & = 5 \\ 2 n & = - 5 \\ n & = \frac { - 5 } { 2 } \end{aligned}\), \(\begin{aligned} 2 ( n + 8 ) - 6 & = 2 \left( \color{Cerulean}{- \frac { 5 } { 2 }}\color{Black}{ +} 8 \right) - 6 \\ & = 2 \left( \frac { 11 } { 2 } \right) - 6 \\ & = 11 - 6 \\ & = 5 \quad\color{Cerulean}{}\end{aligned}\). Solving Literal Equations 6) More than 12.5 weeks. 1.2 Notes: Solving Linear Equations. I would suggest 7 to 8 minutes be allotted for each station. This leads to the following new rule: when multiplying or dividing by a negative number, reverse the inequality. Solve: \(\frac { 2 } { 3 } x + \frac { 1 } { 2 } = - \frac { 5 } { 6 }\). Dividing by \(0\) is undefined and multiplying both sides by \(0\) results in the equation \(0 = 0\). Solving equations and inequality worksheets is helpful as they are used to compare numbers and decide the range or ranges of values that fulfill the circumstances of a given variable. 7) At least 15 times 8) No solution.
