Destiny is asked about her age. She answers as follows. "My age is 3 years more than twice the age of my younger brother. The sum of our ages is 42 years."

Destiny is 9 years old I think

Step-by-step explanation:

29

Step-by-step explanation:

since her age is 3 more than twice her brothers age we'll subtract 3

42 - 3 = 39

since shes twice her brothers age theres actually 3 numbers. her brother's age which is the base number, and her age, which is is that times 2. so in order to get her brothers age we divide by 3

39 ÷ 3 = 13

since shes twice his age + 3 we'll multiply by 2, then add 3

13 × 2 + 3 = 29

I hope this isnt too complicated! I tried to simplify it but I think it came out more confusing than I intended
