The way to solve this question is…

step. 1 I started with five and thought of what you add to five to get 24.

step. 2 when you figure out what you add to five to get 24 you put the numbers in the circles

until you get 24.

step. 3 because there are three lines you have to figure out those too.

step. 4 when you have figured out the three lines and you double check if they are correct

and if they are you are finished.

here is my example.

5 + 10 + 9 = 24

9 + 8 + 7 = 24

AND

8 + 6 + 10 = 24
