Question

TÌM X

\(\frac{X+1}{2015}+\frac{X+2}{2014}+\frac{X+3}{2013}+\frac{X+4}{2012}=4\)\(4\)

Answer 1

\(\frac{x+1}{2015}\)+\(\frac{x+2}{2014}\)+\(\frac{x+3}{2013}\)+\(\frac{x+4}{2012}\)=44

\(\frac{x+1}{2015}\)+1+\(\frac{x+2}{2014}\)+1+\(\frac{x+3}{2013}\)+1+\(\frac{x+4}{2012}\)+1=44+4

\(\frac{x+2016}{2015}\)+\(\frac{x+2016}{2014}\)+\(\frac{x+2016}{2013}\)+\(\frac{x+2016}{2012}\)=48

(x+2016)(\(\frac{1}{2015}\)+\(\frac{1}{2014}\)+\(\frac{1}{2013}\)+\(\frac{1}{2012}\))=48

Answer 3

\(\Rightarrow\frac{x+1}{2015}=1;\frac{x+2}{2014}=1;\frac{x+3}{2013}=1;\frac{x+4}{2012}=1\)

\(vì\)\(1+1+1+1=4\)

\(\text{mUỐN PHÂN SÓ =1 THÌ TỬ SỐ = MẪU SỐ}\)

\(X+1=2015\)

\(X=2014\)
