Answer:

Mike = 3

Robert = 9

Step-by-step 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 :)
