Question

43 + (9-21)=317-(x+ 317 )

Trần Khánh Linh · Accepted Answer

$43+\left(9-21\right)=317-\left(x+317\right)$

$43+9-21=317-x-317$

$31=317-317-x$

$31=0-x$

$\Rightarrow x+0=-31$

$x=\left(-31\right)-0$

$x=-31$Câu trả lời: $43+\left(9-21\right)=317-\left(x+317\right)$

$43+9-21=317-x-317$

$31=317-317-x$

$31=0-x$

$\Rightarrow x+0=-31$

$x=\left(-31\right)-0$

$x=-31$

Nguyễn Thanh Hằng · Answer

$43+\left(9-21\right)=317-\left(x+317\right)$

$43+\left(-12\right)=317+x-317$

$31=317+x+\left(-317\right)$

$31=317+\left(-317\right)+x$

$31=0+x$

$31=x$

$\Leftrightarrow x=31$

Vậy $x=31$ là giá trị cần tìmCâu trả lời: $43+\left(9-21\right)=317-\left(x+317\right)$

$43+\left(-12\right)=317+x-317$

$31=317+x+\left(-317\right)$

$31=317+\left(-317\right)+x$

$31=0+x$

$31=x$

$\Leftrightarrow x=31$

Vậy $x=31$ là giá trị cần tìm

co be bo cap · Answer

$43$ $+$ $\left(9-21\right)$ $=$ $317$ $-$ $\left(x+317\right)$

$43$ $+$ $\left(9-21\right)$ $=$ $317$ $-$ $x-317$

$43+\left(-12\right)$ $=$ $317-317-x$

$31$ $=$ $0-x$

$0+x=31$

$x$ $=$ $31-0$

$x$ $=$ $31$Câu trả lời: $43$ $+$ $\left(9-21\right)$ $=$ $317$ $-$ $\left(x+317\right)$

$43$ $+$ $\left(9-21\right)$ $=$ $317$ $-$ $x-317$

$43+\left(-12\right)$ $=$ $317-317-x$

$31$ $=$ $0-x$

$0+x=31$

$x$ $=$ $31-0$

$x$ $=$ $31$
