How do you solve 15>= 8 + b - 12?

Jun 21, 2016

$b \le 19$

Explanation:

Treat inequalities in the same way as equations, except if you multiply or divide by a negative number, then the inequality sign has to change around.

$\text{ } 15 \ge 8 + b - 12$

$15 + 12 - 8 \ge b$

$\text{ } 19 \ge b$

This is easier written as $b \le 19$
