Question

1) The sum of the numerator and the denominator
of a fraction is equal to 7. Four times the numerator is 8 less than 5 times the denominator ...find the fraction
​

Answer 1

Answer:

Step-by-step explanation:

let fraction be x/y

given x+y = 7........eqn 1

       4x=5y-8

       that is 5y-4x=8..........eqn 2

to equate coef of y multiply eqn 1 by 5

          so 5(x + y = 7)

             =5x+5y=35.............eqn 3

sub eqn 2 from eqn 3

 =9x =27

x=3

 substituting value of x in eqn 1

x + y =7

 3+y=7 

y=4

so the fraction is 3/4
