n=7
OpenStudy (anonymous):
basically the goal here is to isolate n so its alone on one side we can start by removing the constant -7 from the left side this can be done by adding 7 to both sides of the equation, because -7+7=0 this leaves you with 5n=35 now you want to isolate n by getting rid of the 5 this can be done by dividing 5 on both sides 5/5=1 leaving you with n=7 @sara6274 welcome to OS, please read http://openstudy.com/code-of-conduct
