Xx1000=12000
X =12000:1000
X=12
k cho mình nha!
\(125x+876x-x=12000\)
\(\Leftrightarrow125x+876x-1x=12000\)
\(\Leftrightarrow x\left(125+876-1\right)=12000\)
\(\Leftrightarrow1000x=12000\)
\(\Leftrightarrow x=12000\div1000\)
\(\Leftrightarrow x=12\)
\(\text{Vậy }x=12\)
Xx125+Xx876-X=12000
Xx125+Xx876-Xx1=12000
Xx(125+876-1)=12000
Xx1000=12000
X=12000:1000
X=12
Xx125+Xx876-X=12000
Xx125+Xx876-Xx1=12000
Xx(125+876-1)=12000
Xx(1001-1)=12000
Xx1000=12000
X =12000:1000
X=12
125x+876x-x=12000
<=>125x+876x-1x=12000
<=>1000x=12000
<=>x=12000:1000
=>x=12
cảm ơn tất cả mọi người đã giúp mình
TL :
x = 12
