tk nha bạn

thank you bạn

(^_^)

X x (125+876-1) = 12000

X x 1000            = 12000

X                        = 12000 : 1000

X                        = 12

thanks you nhé

\(y\times125+y\times876-y=12000\)

\(=>y\times\left(125+876-1\right)=12000\)

\(=>y\times1000=12000\)

\(=>y=12000:1000\)

\(=>y=12\)

k cho mình nha!
