9 - 5n + 1 = 15
what does n equal?

n = -1

Step-by-step explanation:

9 - 5n + 1 = 15

-5n + 1 = 6 (Subtract 9 from both sides)

-5n = 5 (Subtract 1 from both sides)

n = -1  (Divide by negative five on both sides)

The value of n is -1.

Step-by-step explanation:

First, you have to move all the unrelated variable to one side by subtraction 10 to both sides :

9 - 5n + 1 = 15

10 - 5n = 15

10 - 5n - 10 = 15 - 10

-5n = 5

Next, you have to to divide -5 to both sides in order to find the value of n :

-5n = 5

-5n ÷ -5 = 5 ÷ -5

n = -1
