Alex is 72 years old and will is 4 years old how many years will it take untill Alex is only 5 times as old as will?

13 years

Step-by-step explanation:

x: The number of years until Alex is 5 times older than Will.

Now Later

Alex: 72 72+x

Will: 4 4+x

72+x = 5 (4+x) Alex's age (72) plus x is 5 times older than Will's age plus x

72+x = 20+5x Just solve the equation

52 = 4x

x = 13 (years)

Answer: It will take 13 years for Alex to be 5 times as old as will
