Question

marc and his friend david are comparing ages. they figure out if they double marc age from 3 years ago and add it to david's current age, the sum is 26. if david's is currently 8 years old, determine how old marc is

Answer 1

Marc is 12

Using david’s age we can find what marc’s age is from three years ago by working backwards.

26-8= 18
18/2 = 9
Three years ago marc was 9 so now he is 12 (since 9+3 = 12)
