Answer 4

( x - 1/2 ) . 5/3 = 7/4 - 1/2

( x - 1/2 ) . 5/3 = 5/4

( x - 1/2 )  = 5/4 : 5/3

x - 1/2 = 3/4

x = 3/4 + 1/2

x = 5/4 hoặc 1,25

6/13 : ( 1/2 + x ) = 15/39

( 1/2 + x ) = 6/13 : 15/39

1/2 + x = 6/5

x = 6/5 -1/2

x = 7/10

16/3 : ( 1/2 + x ) = 15/39

( 1/2 + x ) = 16/3 : 15/39

1/2 + x = 208/15

x = 208/15 - 1/2

x = 401/30
