Answer:
Problem 1: n = 16
Problem 2: n = -1
Step-by-step explanation:
Problem 1:
-3n + 48 = 0
We solve the equation for n.
First, subtract 48 from both sides.
-3n = -48
Now divide both sides by -3. This cancels out the negative on both sides:
n = 16
-2n + 10 -5n = 17
First, combine the terms with n:
-7n + 10 = 17
Now, combine the numbers that don't have n (subtract 10 from both sides).
-7n = 7
n = -1
Answer:
In question 1, n= 16
In question 2, n = -1
Step-by-step explanation:
Question 1: -3n + 48 =0
Question 2: -2n + 10 - 5n = 17
To find n in Question 1
-3n + 48 =0
3n = 48
n = 48/3
n = 16
To find n in Question 2
-2n + 10 - 5n = 17
-2n - 5n = 17 - 10
-7n = 7
n = 7/-7 = -1
n = -1
Therefor the value of n in question 1 is 16
and value of n in question 2 is -1
