X x 2 + X x 3 = 200
X x ( 2 + 3 ) = 200
X x 5 = 200
X = 200 : 5
X = 40

\(x.2+x.3=200\)
\(x.\left(2+3\right)=200\)
\(x.5=200\)
\(x=200\div5\)
\(x=40\)
\(x\)\(\times\) \(2\)\(+\)\(x\)\(\times\)\(3\)\(=\)\(200\)
\(x\)\(\times\)\(\left(2+3\right)\)\(=\)\(200\)
\(x\)\(\times\) \(5\) \(=\)\(200\)
\(x\) \(=\)\(200\)\(\div\)\(5\)
\(x\) \(=\) \(40\)
X x 2 + X x 3 = 200
X x ( 2 + 3 ) = 200
X x 5 = 200
X = 200 : 5
X = 40
Vậy X = 40
