Question

Tính gần đúng nghiệm của hpt:

\(\int^{x^2\left(x+2014\right)\left(y-2013\right)=9}_{x^2+x+xy=6}\)

Answer 1

\(\int^{x\left(x+2014\right)x\left(y-2013\right)=9}_{x\left(x+2014\right)+x\left(y-2013\right)=6}\Leftrightarrow\int^{ab=9}_{a+b=6}\Leftrightarrow\int^{a=3}_{b=3}\Leftrightarrow\int^{x^2+2014x=3}_{x\left(y-2013\right)=3}\Leftrightarrow\int^{x=}_{y=}\)
