Question: 50. Evaluate the equation: 3n + 18 = 60, what is the value of N?
Answer:
a. 15
b. 16
c. 14
d. 13
Solution:
#To find the value of n
3n+18=60 (Given)
3n=60-18
3n=42
3n/3=42/3 (Divide both sides by 3)
n=14
#Check first
#Substitute n by 14
#If n=14
3n+18=60
3(14)+18=60
(42)+18=60
60=60
Explanation: They are both equal and correct to each other.
