Alex will be twice as old as Bill in three years. Write an expression which correctly describes
Alex’s present age in terms of Bill’s present age, b?
Alex’s present age in terms of Bill’s present age, b?
b = Bill's age in 3 years
2b = Alex's age in 3 years {Alex will be twice as old as Bill in 3 years}
If Bill is b in 3 years, then he is b - 3 right now.
Also, if Alex is 2b in 3 years, then he is 2b - 3 right now.
Alex's present age is 2b - 3
