Step-by-step explanation:

the first step you would do is add 6 to both sides. this gets -3n by itself on one side. adding 6 cancels out the -6

21 = -3n

then you'd divide by -3 to cancel out the multiplication and gets n by itself

n = -7

Answer:

The first step should be to add 6 on both sides since you want to isolate the variable.

Step-by-step explanation:

15= -3n-6

15+6- -3n-6+6

21=-3n

n=-7
