Question

The denominator of a rational number is 1 less than twice the numerator . If 6 is added to both the numerator and the denominator, the number becomes 12/17 . Find the rational number.​

Answer 1

Answer:

let ,

numerator be x

denominator be 2x - 1

x+6/(2x-1)+6 = 12/17

x+6/2x+5 = 12/17

17x + 102 = 10x + 60

17x - 10x = 60 - 102

7x = -42

x = -6

the rational number is -6
