Question

Cho x - 52 = 904 ; y x 6 - y = 20 x 5

Vậy x + y = ?

Answer 1

x-52=904

x     =904+52=956

y*6-y=20*5=100

y*(6-1)=100

y*5=100

y=100/5=20

x+y=956+20=976

Answer 2

x-52=904

x=904+52

x=956

yx6=-y=20:5

yx6-y=4

yx5=4

y=20

x+y=976

Answer 3

x - 52 = 904

x       = 904 + 52

x       = 956 

y x 6 - y = 20 x 5

y x 6 - y = 100

     5 x y = 100 

           y = 100 : 5

           y =20

vậy x + y = 956 +20 = 976
