x-116+403=428
x-116=428-403
x-116=25
x=25+116
x=141
\(x-116+403=428\)
\(x-116\) \(=428-403\)
\(x-116\) \(=25\)
\(x\) \(=25+116\)
\(x\) \(=141\)
\(x-116+403=428\)
\(x-116=428-403\)
\(x-116=25\)
\(x=25+116\)
\(x=141\)
Vậy x = 141
\(x-116+403=428\)
\(x-116=428-403\)
\(x-116=25\)
\(x=25+116\)
\(x=141\)
k nhé
