Answer:

n = 25/2

Step-by-step explanation:

First, you would want to subtract 7 from both sides of the equation.  That would cancel the 7s out and 12-7 = 5. So now the equation looks like this: 2/5n = 5.  Next, you would multiply both sides by 5/2, which is the reciprocal of 2/5. Now you have n= 5*(5/2). Lastly, you would just want to multiply 5*5 to get 25 and the 2 will just stay the same. So n = 25/2.
