I' stumped on this formula question, How do I solve for N w/o additional information??

dolebear law states the relationship between the rate at which snowy tree crickets chirp and the air temp of their enviroment. The formula is: T=50 =N-40/4 where T is a temperature in degrees Farenheit and N is a number of chirps per minute. If T=58 degrees, find the number of chirps per minute.
 
How do I solve for N?

T=50 =N-40/4
Is not a formula. It is three terms joined by two equal signs.
Proof, edit, and resubmit.

T = (N-40)/4
4T = N-40
4T + 40 = N
 
Plug in T =  50 (or 58, whichever it is) and compute the answer

I'm showed the answer is 72 in my book, however I do not understand how this answer was solved. Please show me the steps to arrive at this answer.

You will need to correct your equation for T, because the answer I gave you will not equal 72 for T=58.  So obviously T = (N-40)/4 is not the correct equation.
