Answer:
x=7
Step-by-step explanation:
=> [(x - 3) + 1] / (x + 3) = 1/2
=> (x - 2) / (x + 3) = 1/2
=> x + 3 = 2 (x - 2)
=> x + 3 = 2x - 4
=> x - 2x = -4 -3
=> -x = -7
=> x = 7
The number = x - 3/x = 7-3/7 = 4/7

let the numerator be x
So the fraction would be x/x+3
ATQ x+2/x+3+5
= x+2/x+8
now, x+2/x+8=1/2(given)
By cross Multiplication
2(x+2) = 1(x+8)
2x+4=x+8
2x-x=8-4
x=4
The rational number is x/x+3
which is equal to 4/7
