$n=\frac{386x-75}{5}$

Step-by-step explanation:

Add like terms

$-35x+3\cdot \frac{3}{5}x-22\cdot \:2x-15=n$

Add 15 on both sides

$-35x+\frac{9}{5}x-44x-15+15=n+15$

Simplify

$-35x+\frac{9}{5}x-44x=n+15$

Multiply sides by 5

$-35x\cdot \:5+\frac{9}{5}x\cdot \:5-44x\cdot \:5=n\cdot \:5+15\cdot \:5$

Simplify

-386x=5n+75

Divide both sides

$\frac{-386x}{-386}=\frac{5n}{-386}+\frac{75}{-386}$

You will get

$x=-\frac{5n+75}{386}$

Then you will solve for n using x

Multiply both sides by 386

$\frac{386\left(5n+75\right)}{386}=386x$

Simplify

5n+75=386x

Subtraction

5n+75-75=386x-75

Simplify

5n=386x-75

Divide by 5 to get n

$\frac{5n}{5}=\frac{386x}{5}-\frac{75}{5}$

$n=\frac{386x-75}{5}$
