Answer 2

Answer

7

Step-by-step explanation:

let the denominator =x

numerator is 2 less than the denominator

i.e x-2

=x-2/x

also,

if numerator and denominator is added by 1 it is equal to 3/4

so, i.e

x-2+1/x+1=3/4

(cross multiplication)

4(x-2+1)=3(x+1)

4x-8+4=3x+3

4x-3x=3+8-4

x=7

substitute the value in the x

=7-2/7

=5/7

I hope you under stand the answer
