Solve LaTeX:  \displaystyle | 10 x + 5 | \leq 5

The inequality is an "and" type compound inequality. Setting up the three part inequality gives LaTeX:  \displaystyle  -5 \leq 10 x + 5 \leq 5 . Doing the same thing to all three parts gives LaTeX:  \displaystyle  -10 \leq 10 x \leq 0 . Isolating LaTeX:  \displaystyle x gives LaTeX:  \displaystyle  -1 \leq x \leq 0 .
