k cho mình nha!
\(125x+876x-x=12000\)

tk nha bạn
thank you bạn
(^_^)
X x (125+876-1) = 12000
X x 1000 = 12000
X = 12000 : 1000
X = 12
Y x 125 + Y x 876 - Y = 126722
Các bạn giải gấp giúp mình với
Mình cảm ơn các bạn trước nha
y x 125 + y x 876 - y x 1 = 126722
y x (125 + 876 - 1) = 126722
y x 1000 = 126722
y = 126,722
~hok tot~
Y x 125 + Y x 876 - Y = 126722
=> Y( 125 + 876 - 1 ) = 126722
=> 1000Y = 126722
=> Y = 126,722
Tìm y:
y × 125 + y × 876 - y = 12 000
y × ( 125 + 876 - 1 ) = 12 000
y × 1000 = 12 000
y = 12 000 : 1000
y = 12
Vậy x bằng 12
y*125+y*876-y=12000
<=>y*(125+876-1)=12000
<=>y*1000=12000
<=>y=12
