Answer: 510.
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 :)
