x + 1/100 + x + 2/101 = x + 3/102 - 1
<=> x + 1/100 - 1 + x + 2/101 - 1 = x + 3/102 - 1 - 2
<=> x - 99/100 + x - 99/101 = x - 99/102 - 2
<=> x - 99/100 + x - 99/101 - x - 99/102 = -2
<=> (x - 99)(1/100 + 1/101 - 1/102) = -2
<=> x - 99 = -2/1/100 + 1/101 - 1/102
<=> x = -2/1/100 + 1/101 - 1/102 + 99
Bạn chịu khó bấm máy hộ mình, số to quá
