Answers
Given : bike costs (35ab – 30a – 7b + 6) pesos
To be paid in (5a – 1) months.
To Find : monthly payment
Solution:
monthly payment = x pesos
Number of months = (5a - 1)
=> Total payment = x (5a - 1) pesos
Total cost = 35ab – 30a – 7b + 6 pesos
Equate
=> x (5a - 1) = 35ab – 30a – 7b + 6
=> x = (35ab – 30a – 7b + 6 ) / (5a - 1)
35ab – 30a – 7b + 6
= 35ab - 7b - 30a + 6
= 7b(5a - 1) - 6(5a - 1)
= (5a - 1)(7b- 6)
monthly payment = (5a - 1)(7b- 6) / (5a - 1)
= (7b- 6)
Monthly payment will be (7b - 6) pesos

= 7b(5a - 1) - 6(5a - 1)
= (5a - 1)(7b- 6)
monthly payment = (5a - 1)(7b- 6) / (5a - 1)
= (7b- 6)
Monthly payment will be (7b - 6) pesos
