Ta có: x-10/30 + x-14/43 + x-5/95 + x-148/8 = 0
ð X-10/30 - 3 + x-14/43 - 2 + x-5/95 - 1 + x-148/8 + 6 = 0
ð X-10-90/30 + x-14-86/43 + x-5-95/95 + x-148+48/8 = 0
ð X-100/30 + X-100/43 + X-100/95 + X-100/8 = 0
ð {X-100} . {1/30 + 1/43 + 1/95 + 1/8} = 0
Vì: /30 + 1/43 + 1/95 + 1/8 khác 0
ð X-100 = 0
ð X = 100
