\(100+23+x=469\) \(567-x=278-35\) \(x-120=403+60\)
\(123+x=469\) \(567-x=243\) \(x-120=463\)
\(x=469-123\) \(x=567-243\) \(x=463+120\)
\(x=346\) \(x=324\) \(x=583\)
Vậy x = 346 Vậy x = 324 Vậy : x = 583
a) 100+23+x=469
\(\Leftrightarrow123+x=469\)
\(\Leftrightarrow x=469-123\)
\(\Leftrightarrow x=346\)
b) 567-x = 278-35
\(\Leftrightarrow567-x=243\)
\(\Leftrightarrow x=567-243\)
\(\Leftrightarrow x=324\)
