Question

19.5 - X x 6.3 = 11.625

Answer 1

=> x.6,3 = 19,5 - 11,625

=> x.6,3 = 7,875

=> x = 7,875 : 6,3

=> x = 1,25

Vậy x = 1,25

Answer 2

19.5 - X x 6.3 = 11.625 

6.3x X - 19.5 = 11.625

6.3x X            =19.5 -11.625

6.3x X             =7.875

        X             = 7.875 : 6.3

        X              =1.25

thử lại :19.5 -1.25 x 6.3 =11.625
