Question

tìm y

y x 12 +y x 13 - y = 4872

Answer 1

yx12+yx13-y=4872

yx(12+13-1)=4872

yx24=4872

y=4872:24

y=203

vay y=203

Answer 2

y x 12 + y x 13 - y = 48,72

y x ( 12 + 13 - 1 ) = 48,72

y x 24 = 48,72

y = 48,72 : 24

y = 2,03

Answer 3

y x 12 + y x 13 - y = 4872

 y x 12 + y x 13 - y x 1 = 4872

 y x ( 12 + 13 - 1 ) = 4872

y x 24 = 4872

y = 4872 : 24

y = 203
