125. (-6). x. (-8)= 12000
Tìm x: x × 125 + x × 876 - x = 12000
x×125 + x×876 - x=12000
x × (125 + 876 - 1)=12000
x × 1000=12000
x=12000 : 1000
x=12
Vậy x=12
Tìm x: x × 125 + x × 876 - x = 12000
χ x (125+873-1)=12000
χ x 1000=12000
x=12000:1000
x=12
y x 125 + y x 876 - y = 12000
\(y\times125+y\times876-y=12000\)
\(=>y\times\left(125+876-1\right)=12000\)
\(=>y\times1000=12000\)
\(=>y=12000:1000\)
\(=>y=12\)

tk nha bạn
thank you bạn

X x (125+876-1) = 12000
X x 1000 = 12000
X = 12000 : 1000
X = 12
tìm x
4057+(X : 38 ) = 20395. 3132 - 19832 : X= 3058
1260 : X x 215=7740. X x 125 + X X876 - X = 12000
4057+(X:38) = 20395
X:38 = 20395-4057
X:38= 16338
X=16338 x 38
X= 620844
12 x 125 x 24 x 50
25 x 125 x 6 x 8 x 4
12 x 125 x 24 x 50
= (12 x 50) x (125 x 24)
= 600 x 3000
= 1800000.
