Question

Please explain it in detail

Answer 1

let the numerator be x

so,it is

x/(x+4)...........1 equation

(x+2)/(x+4+3)=3/4...........2 equation

2 equation

(x+2)/(x+4+3)=3/4

(x+2)/(x+7)=3/4

4(x+2)=3(x+7)

4x+8=3x+21

4x-3x=21-8

x=13........value of x

now substitute the value of x in 1 equation

x/(x+4)

13/(13+4)

13/17...........the original value

ans:13/17
