tk nha bạn
thank you bạn

\(y\times125+y\times876-y=12000\)
\(=>y\times\left(125+876-1\right)=12000\)
\(=>y\times1000=12000\)
\(=>y=12000:1000\)
\(=>y=12\)

k cho mình nha!
\(125x+876x-x=12000\)
\(\Leftrightarrow125x+876x-1x=12000\)
\(\Leftrightarrow x\left(125+876-1\right)=12000\)
\(\Leftrightarrow1000x=12000\)
\(\Leftrightarrow x=12000\div1000\)
\(\Leftrightarrow x=12\)
\(\text{Vậy }x=12\)

4057+(X:38) = 20395
X:38 = 20395-4057
X:38= 16338
X=16338 x 38
X= 620844

125.(-6).x.(-8)=12000
125.[(-6).(-8)].x=12000
145.48.x=12000
6000.x=12000
x=12000:6000
x=2

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

x + 223 = 876 - 326
x + 223 = 550
x = 550 - 223
x = 327
Vậy x = 327

=>1000x=12000
hay x=12
x×125 + x×876 - x=12000
x × (125 + 876 - 1)=12000
x × 1000=12000
x=12000 : 1000
x=12
Vậy x=12
