60,36 : X + 43,14 : X = 45
(60,36 + 43,14) : x = 45
103,5 : x = 45
x = 103,5 : 45
x = 2,3
60,36 : X + 43,14 : X = 45
( 60,36 + 43,14 ) : X = 45
103,5 : X = 45
X = 103,5 : 45
X = 2,3
Vậy X = 2,3
\(60,36\div x+43,14\div x=45\)
\(\Leftrightarrow\)\((60,36+43,14)\div x=45\)
\(\Leftrightarrow\)\(103,5\div x=45\)
\(\Leftrightarrow\)\(x=103,5\div45\)
\(\Leftrightarrow\)\(x=2,3\)
