Answer:
n = 6+x
Step-by-step explanation:
Given that:
Amy is 6 years old than her brother Leo
Let consider the age of Leo to be x since we are not yet told how old is Leo
Then Amy is 6+x
Now, we know that Leo is seven years old,
i.e x = 7
If n stands for Amy's age,
Then, the algebraic expression showing how old is Amy's age can be expressed as n = 6+x
Amy's age (n) = 6+7
Amy's age (n) = 13
