Ana's age is 8 year less than 4 times her sister's age.how old is ana if her sister is 5 year old.
To find Ana's age, you need to substitute the value of her sister's age into the expression "4n-8", where n represents her sister's age.
Given that Ana's sister is 5 years old, substitute n=5 into the expression:
4n-8
= 4(5) - 8
= 20 - 8
= 12
Therefore, Ana is 12 years old.
