Answer :
Answer:
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)
Answer:
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
