Question

\(x\times2+x\times3+x\times4+x=2013\)

Answer 1

x×2+x×3+x×4+x=2013

x×(1+2+3+4)=2013

x×10=2013

⇔x=2013/10 

Answer 2

\(x\times2+x\times3+x\times4+x=2013\)

\(x\times\left(1+2+3+4\right)=2013\)

\(x\times10=2013\)

\(\Leftrightarrow x=\frac{2013}{10}\)

P/s tham khảo nha

Answer 3

X x 2 + X x 3 + X x 4 + X = 2013

X x ( 2 + 3 + 4 + 1 ) = 2013

X x 10 = 2013

X = 2013 : 10

X = \(\frac{2013}{10}\)

Answer 4

\(x\cdot2+x\cdot3+x\cdot4+x=2013\)

\(x\cdot\left(2+3+4+1\right)=2013\)

\(x\cdot10=2013\)

\(x=2013:10=201,3\)

Answer 5

\(x\times2+x\times3+x\times4+x=2013\)

\(\Rightarrow x\times\left(2+3+4+1\right)=2013\)

\(\Rightarrow x\times10=2013\)

\(\Rightarrow x=2013\div10\)

\(\Rightarrow x=201,3\)
