1+2y/18=1+6y/6x
=> 1+2y+1+6y/18+6x
=> 2+8y/2(9+3x)
=> 2(1+4y)/2(9+3x)
=> 1+4y/9+3x
Ma 1+4y/24=1+4y/9+3x
=> 9+3x=24
=> x=5
Ta có: 1+2y = 1+6y = 1+2y+1+6y = 2+8y
18 6x 18+6x 18+6x
Mặt khác: 1+4y = 2+8y
24 48
TH1 Nếu x = 0 thì 1+2y = 1+6y = 0. Vậy 1+2y = 1+6y = 0 .Vậy 2y = -1.Vậy y=-1/2
18 24 4y = -1.Vậy y=-1/4
TH2 Nếu x khác 0 thì 18 + 6x = 48. Vậy 6x=48-18=30.Vậy x=5
(1+4y) * 6x = (1+6y) * 24
(1+4y) * 30 = (1+6y) * 24
30 + 120y = 24 + 144y
30 - 24 = 144y-120y
6 = 24y
Vậy y = 6:24 = 1/4
Vậy y = 1/4 và x=5
