Question

x nhân 15 + x nhân 48=160020

45: x + 55 : x =892

Answer 1

X x 15 + X x 48 = 160020

X x ( 15 + 48 ) = 160020

X x 63 = 160020

        X = 160020 : 63

        X = 2540

45 : x + 55 : x = 892

( 45 + 55 ) : x = 892

100 : x = 892

Tự tính

Answer 2

45+55:x=892

55:x=892-45

55:x=847

x=847 x 55

x=46585

Answer 3

x*15+x*48=160020

x(15+48)=160020

x*63=160020

=>x=2540

45/x+55/x=892

(45+55)/x=892

100/x=892

=>x=0,1121..

Answer 4

X x 15 + X x 48 = 160020

X x ( 15 + 48 ) = 160020

X x 63 = 160020

        X = 160020 : 63

        X = 2540

45 : x + 55 : x = 892

( 45 + 55 ) : x = 892

100 : x = 892

=> x = 100/892
