Question

Robert is 6 years older than his brother Mike. In three years he will be twice as old as Mike. How old are each of them now?

Also show the work on how to do this, thanks!

Answer 1

Mike = 3

Robert = 9

Explanation:

R = Robert

M = Mike

Mike is 6 years younger than Robert

R = M + 6

Add 3 years to both sides

R + (3) = 2M + (3)

Represent that Robert is now twice as old as Mike

2M + 3 = M + 3 + 6

Solve + Subtract the 3 years

2M + 3 = M + 9

M = 6 - 3 = 3

R = 12 - 3 = 9

Hope this helps :)
