now let's flip this equation to make things easier
now move -3 to the other side
when we move -3 to the other side it turns into positive 3
now add the values on both sides
n + 2n will be equal to 3n and 9 + 3 will be equal to 12
now move 3 to the other side
the multiplication sign that binded 3 and n together will change into division when moved to the other side
when we divide 12 and 3 we will get 4
so final answer is 4
hope that helps !
