Step-by-step explanation:
Madison is 7 less than four times as old as Paige. The product of their ages is 47 more than the sum of their ages. How old are Madison and Paige?
- Let M represent Madison and P represent Paige.
- So the first equation will be M = 4 P – 7
- So second equation will be P X M = P + M + 47
- Now substituting for M in the above equation we get
- P(4P – 7) = P +5 (4P – 7) + 47
- 4 P^2 – 7P = P + 4P – 7 + 47
- 4P^2 – 7P = 5P + 40
- 4P^2 – 12 P – 40 = 0
- P^2 – 3P – 10 = 0
- P^2 – 5P + 2P – 10 = 0
- P(P – 5) + 2(P – 5) = 0
- (P – 5) (P + 2) = 0
- P = 5 , - 2 (since age is not negative)
- So age of Paige is 5 years.
- Age of Madison will be M = 4P – 7
- = 4(5) – 7
- = 20 – 7
- = 13
- So we have Madison is 13 years old and Paige is 5 years.
