a,52/3(2/3+x)=41/3 b,2.x-2/3=2/3

2 bình luận về “a,52/3(2/3+x)=41/3 b,2.x-2/3=2/3”

1. a,

   52/3(2/3+x)=41/3

   2/3+x=41/3:52/3

   2/3+x=41/3xx3/52

   2/3+x=41/52

   x=41/52-2/3

   x=123/156-104/156

   x=19/156

   Vậy x=19/156

   b,

   2*x-2/3=2/3

   2*x=2/3+2/3

   2*x=4/3

   x=4/3:2

   x=2/3

   Vậy x=2/3
