Question

one year ago a man was 8 times as old as his son now his age is equal to the square of his son's age​

Answer 1

the man is now 49 and the child is 7

Step-by-step explanation:

equation 1 is x =y²

where x and y are current ages

eq 2 is x-1 = 8(y-1)

solve these two and you'll get 2 values of x and y that are 1,1 and 49,7. obviously they cant be both 1 year olds so the other one is the answer

Hope it helps : )
