7/9 is the answer I believe
Answer:
(3-2h)^3 + (3-2h)^4 = (3-2h^2)^3 (1 + (3-2h^2))
total of ages now is 67 + 4 + 4 = 75
S=shelly
M= Michelle
Michelle is 3 yrs younger than Shelly so use S-3
S +M = 75
replace M with S-3 to get:
S +S-3=75
2S=78
s=39
So shelly is 39
Michelle is 3 years younger = 39-3 = 36
The answer is 2.5 just set it up and cross multiply then divide
