Answer:
15
Step-by-step explanation:
AS THEY HAVE SAID THAT NUMERATOR IS 3 LESS THAN DENOMINATOR WE THE FRACTION AS :
X-3/X
NOW THEY HAVE INCREASED TH DENOMINATOR BY 5 AND REDUCED THE NUMERATOR BY 2 SO THAT WHICH WILL BE EQUAL TO 1/2 SO WWE GET THE EQUATIO LIKE:
X-3-2/X+5 = 1/2
X-5/X+5 = 1/2
by cross multplication
2(X-5) = 1(X+5)
2X-10 = X + 5
2X-X = 5 +10
X=15
