5 × x + 6 / 7 = 11 /12 x : 6 / 5 – 11 / 3 = 3 /5

2 bình luận về “5 × x + 6 / 7 = 11 /12 x : 6 / 5 – 11 / 3 = 3 /5”

1. Giải đáp:

   5 xx x + 6/7  = 11/12

   5 xx x = 11/12 – 6/7

   5 xx x = 5/84

   x = 5/84 : 5

   x = 5/84 xx 1/5

   x=1/84

   Vậy x=1/84

   $\\$

   x : 6/5 – 11/3 = 3/5

   x : 6/5 = 3/5 + 11/3

   x : 6/5 = 64/15

   x = 64/15 . 6/5

   x=128/25

   Vậy x=128/25

    

    

   Trả lời
2. 5 xx x + 6/7 = 11/12

   5 xx x = 11/12 – 6/7

   5 xx x = 5/84

   x = 5/84 : 5

   x= 1/84

   _______________________________

   x : 6/5 – 11/3 = 3/5

   x : 6/5 = 3/5 + 11/3

   x : 6/5 = 64/15

   x = 64/15 xx 6/5

   x = 128/25
