~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
![(w)/(5) = 3](https://img.qammunity.org/2021/formulas/mathematics/college/6qtcd45b9xub83fr73fsof572yd3p65gxg.png)
Multiply both sides by 5.
![w = 3 * 5](https://img.qammunity.org/2021/formulas/mathematics/college/jmnn5j2i9xsrbr03fdg7x4cselor7zjh79.png)
Multiply 3 and 5 to get, you guessed it, 15!
