what is n/3 - 5 = 2 ???? PLEASE HELP ME!?

n/3=2+5

n/3=7

n=3*7

n=21

n/3 - 5 = 2
n/3 -5+=2+5
n/3 x3 =7x3
n=21

n
- - 5 = 2
3

n
- = 2 + 5
3

n
- = 7
3

n = 7 x 3

n = 21

21 is correct

n/3 -5 = 2
n/3 = 2 + 5 = 7
(n/3)*3 = 7*3
n = 21

(n/3 - 5)+5 = 2+5 (Add 5 to both sides)
n/3 * 3 = (2+5) *3 (Mult. both sides by 3)
n = (2+5) *3
n = (7) *3
n=21

It's a equation!

2 plus 5 = n/3, 7 = n/3, n = 21

n=21
