Michael is 63 years younger than Dana. 7 years ago, Dana's age was 4 times Michael's age. How old is Michael now?
Answered by Ms. Sue
63 - 7 = 56

56 / 4 = 14

14 + 7 = ?

Answered by Reiny
Present age:
Dana ----- x
Michael ---- x - 63

7 years ago:
Dana ---- x-7
Michael --- x-63-7 = x-70

x-7 = 4(x-70)
x-7 = 4x - 280
-3x = -273
x = 91

So Dana is now 91 and Michael is 28

check:
7 years ago , Dana was 84 and Michael was 21
Was Dana 4 times as old as Michael ?? , YES
