This equation can be rearranged to give:

$g = 24 - 4 n$ $g = 24 - 4n$

or

$n = 6 - \frac{g}{4}$ $n = 6 - g/4$

First divide both sides of the equation by $5$ $5$ to get:

[1] $24 = g + 4 n$ $24 = g + 4n$

Then subtract $4 n$ $4n$ from both sides to get:

$g = 24 - 4 n$ $g = 24 - 4n$

Starting from equation [1], subtract $g$ $g$ from both sides to get:

$4 n = 24 - g$ $4n = 24 - g$

Divide both sides by $4$ $4$ to get:

$n = 6 - \frac{g}{4}$ $n = 6 - g/4$

How do you solve for each of the variable 120=5g+20n 120=5g + 20n?
