\(\left(22-54\right)+x=-29\)
\(\Leftrightarrow-32+x=-29\Leftrightarrow x=3\)
Vậy............
\(\left(22-54\right)+x=-29\)
\(\Rightarrow-32+x=-29\)
\(\Rightarrow x=\left(-29\right)-\left(-32\right)\)
\(\Rightarrow x=3\)
(22-54)+x = -29
-32 + x = -29
x = -29-(-32)
x = 3
(22-54)+x=-29
(-32)+x=-29
x=(-29)-(-32)
x=3
(22−54)+x=−29(22−54)+x=−29
⇒−32+x=−29⇒−32+x=−29
⇒x=(−29)−(−32)⇒x=(−29)−(−32)
⇒x=3
