Answer: ages after 5 years will be 16 and 17.
Step-by-step explanation:
let their present ages be x and y
according to question
x+y=23
x=23-y.............eqn.1
five years ago:(x-5)(y-5)=42
solving this eqn. by factorising we get
(y+12)(y-11)=0
y+12=0
y=-12...........(age cannot be negative)
so,y=11 and x=23-y=12.
hence there ages after 5 years will be 16 and 17.
mark it as a brainliest answer.
