solve for (n) 4x+8 over 5n = f

Thank you for the opportunity to help you with your question!

(4x +8)/5n =f

Solve for n


Multiply both sides by 5n

((4x +8)/5n ) x 5n= f x 5n

Divide Both sides with f to remove it from the other side to make 5n the subject of the formula

Remember the 5n on the other side cancel each other after division

(4x +8)/f=5n

divide by 5 to get n

n=4x+8 over 5f


Please let me know if you need any clarification. I'm always happy to answer your questions.

does it matter if its n=4x+8 over 5f or f5

Best practice is 5f not f5
