\(x-\left(36-x\right)=52\\ \Rightarrow x-36+x=52\\ \Rightarrow2x=52+36\\ \Rightarrow2x=88\\ \Rightarrow x=88:2\\ \Rightarrow x=44\)
a, <=> x-36+x =52
<=> 2x= 52+36
<=>2x= 88
<=>x =44
Chúc bạn học tốt nha!
\(x-36+x=52\\ \Rightarrow2x=88\Leftrightarrow x=44\)
\(\Leftrightarrow2x=88\)
hay x=44
$x-(36-x)=52$
$36-x=x-52$
$-x-x=-52-36$
$-2x=-88$
$x=44$
Vậy $x=44$
