Problema Solution

The denominator of a fraction is four more than twice the numerator. If both numerator and denominator are increased by ten, the simplified result is 16/29. Find the original fraction.

Answer provided by our tutors

x = numerator

y = denominator

 

y = 2x + 4

 

(x + 10)/(y + 10) = (16/29)

 

=>  (x + 10)/((2x + 4) + 10) = 16/29

(x + 10)/(2x + 14) = 16/29

x + 10 = (32x + 224)/29

29x + 290 = 32x + 224

3x = 66

 

x = 22

 

y = 2(22) + 4 = 48
