# How do you solve 0.75s + 5= 0.50s + 9?

Apr 5, 2018

$s = 16$

#### Explanation:

First, take $0.75 s$ and $0.50 s$ as $\frac{75}{100} s$ and $\frac{50}{100} s$.

Then it becomes

$\left(\frac{75}{100} s\right) + 5 = \left(\frac{50}{100} s\right) + 9$

$\frac{75 s + 500}{100} = \frac{50 s + 900}{100}$

The $100$ on both sides will get cancelled

$75 s + 500 = 50 s + 900$

$75 s - 50 s = 900 - 500$

$25 s = 400$

$s = \frac{400}{25}$

$s = 16$
