Solve the inequalities. Please explain how to do this.
I know that you have to do two equalities or something. I don't remember. Please help!
|2x-5| > or = 57
|-15x+73| < 122
Recall that $\displaystyle |2x-5| \geq 57$ is the same as $\displaystyle 2x-5 \geq 57$ and $\displaystyle 2x-5 \leq -57$, so you have two parts to solve.
$\displaystyle 2x-5 \geq 57 = 2x \geq 62 = x \geq 31$
Now with this in mind, try the others.
