Luna's age= 2*3-1= 5 years old

Answer 2

Answer:

Lina's age is 5 years old

Step-by-step explanation:

Lina is 1 year younger than 3 times his age. So this means that if we multiply Adam's age by 3 and subtract it by 1(since it says 'younger), we will get Lina's age. Since Adam is 2, Lina is 2*3 - 1 = 5 years old.
