Question 201753
<font face="Garamond" size="+2">

*[tex \LARGE \ \ \ \ \ \ \ \ \ \ |5 - 3x| + 3\ \leq\ 7]


First add -3 to both sides:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ |5 - 3x|\ \leq\ 4]


Now divide it into two inequalities (remember to reverse the sense of the inequality when multiplying by a negative number):


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 5 - 3x \leq 4 \ \ \Rightarrow\ \ -3x\ \leq\ -1 \ \ \Rightarrow\ \ x\ \geq\ \frac{1}{3}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 5 - 3x \leq -4 \ \ \Rightarrow\ \ -3x\ \leq\ -9 \ \ \Rightarrow\ \ x\ \geq\ 3]
