Answer:

Leo is 1 year old.

Explanation:

Given:

Lily's age = 5

Leo's age =
3x-14

we need to find the Leo's age.

Solution:

Leo's age =
3x-14

where x ⇒ Lilly age

But Lilly's age = 5 years (given)

So we will substitute the value of x as 2 in Leo's age expression.

On Substituting we get;

Leo's age =
3x-14 = 3*5-14 = 15-14 = 1\ year

Hence Leo is 1 year old.
