Chapter 1, Equations and Graphs - Section 1.7 - Solving Inequalities - 1.7 Exercises - Page 148: 1

a) $\lt$ b) $\leq$ c) $\leq$ d) $\gt$

We just rearrange each of the inequalities using only one step: a) $x<5$ Subtract both sides by 3: $x-3<2$ b) $x\leq5$ Multiply both sides by 3: $3x\leq15$ c) $x\geq2$ Multiply both sides by -3 (switch the inequality) $-3x\leq-6$ d) $x2$
