Question

(x-3 13/21)+2 10/21=7 2/21

Answer 1

(x-3 13/21)+2 10/21=7 2/21

х-3 13/21+2 10/21= 7 2/21

x - 1 3/21=7 2/21

x=7 2/21+1 3/21

x=8 5/21

Answer 2

(x-3 13/21)+2 10/21=7 2/21

(x-3 13/21)=7 2/21-2 10/21

x-3 13/21=97/21

х = 97/21+ 76/21

х = 173/21=8  5/21

----------------------------------

(8  5/21-3  13/21)+2  10/21= 7  2/21
