# How do you solve the two step inequality -2+r/9> -1  ?

Jul 18, 2016

$r > 9$

#### Explanation:

Treat inequalities in the same way as you would an equation, except that

• you may not cross multiply,
• if you multiply or divide by a negative number, the inequality sign changes around.

$- 2 + \frac{r}{9} > - 1$

$\frac{r}{9} > - 1 + 2$

$\frac{r}{9} > 1 \text{ multiply by 9}$

$r > 9 \text{ this is the solution.}$
