Noah's age is 3 years more than twice tinas age. the sum of their age is 24. how old are they?

Noah is 17 and Tina is 7.

Why?

Let t represent Tina's age.

So, 2t + 3 is Noah's age.

This is your equation;

2t + 3 + t = 24

Now, simplify so t is on one side.

3t = 24 - 3

3t = 21

t = 21/3

t = 7

Tina's age is 7, and Noah (according to the expression made for him) is 17.

Check:

7 + 17 = 24
