# How do you solve for f in 7f + g = 5?

Feb 17, 2016

$f = \frac{5 - g}{7}$

#### Explanation:

to isolate the term with f in it , firstly subtract g from both sides

hence: 7f + g - g = 5 - g

so 7f = 5 - g

now divide both sides by 7

$\frac{\cancel{7} f}{\cancel{7}} = \frac{5 - g}{7}$

$\Rightarrow f = \frac{5 - g}{7}$
