Tìm x 4/5 : x + 1/10 = 13/10 5/6 – x + 2/3 = 4/3

2 bình luận về “Tìm x 4/5 : x + 1/10 = 13/10 5/6 – x + 2/3 = 4/3”

1. 4/5 : x + 1/10 = 13/10

   4/5:x=13/10-1/10

   4/5:x=12/10

   4/5:x=6/5

   x= 4/5:6/5

   x=4/5xx 5/6

   x=20/30

   x=2/3

   Vậy x=2/3

   5/6 – x + 2/3 = 4/3

   5/6-x=4/3-2/3

   5/6-x=2/3

   -x=-5/6+2/3

   -x=-5/6+4/6

   -x=-1/6

   x=1/6

   Vậy x=1/6

   Trả lời
2. 4/5 : x + 1/10 = 13/10

   4/5 : x = 13/10 – 1/10

   4/5 : x = 12/10

   4/5 : x = 6/5

   x = 4/5 : 6/5

   x = 4/5 xx 5/6

   x = 2/3

   Vậy x = 2/3

   _________________________________

   5/6 – x + 2/3 = 4/3

   5/6 – x = 4/3 – 2/3

   5/6 – x = 2/3

   x = 5/6 – 2/3

   x = 5/6 – 4/6

   x = 1/6

   Vậy x = 1/6
