-x + (-53) = -43 - 41
-x + (-53) = -84
-x = -84 - (-53)
-x = -31
=> x = 31.
CHÚC BẠN HỌC TỐT!
\(-x+\left(-53\right)=-43-41\)
\(\Leftrightarrow-x-53=-84\)
\(\Leftrightarrow-x=-84+53\)
\(\Leftrightarrow-x=-31\)
\(\Leftrightarrow x=31\)
\(\text{Vậy }x=31\)
\(-x+\left(-53\right)=-43-41\)
\(-x+\left(-53\right)=-84\)
\(-x=-84-\left(-53\right)\)
\(-x=-31\)
\(=>x=31\)
Vậy \(x=31\)
