Answer 2

Answer:

Liza is 17 years old.

Step-by-step explanation:

Ley 'x' be the age of Liza's younger sister

• As Liza’s age is two more than thrice the age of her younger sister

so the equation of Liza's age will be:

Liza's age = 3x+2

As x = 5 years is Liza's younger sister age

so

Liza's age = 3(5)+2

                 = 15+2

                  = 17 years

Therefore, Liza is 17 years old.
