Question

Tìm x

x + \(\left(\frac{-31}{12}\right)^2\) = \(\left(\frac{49}{12}\right)^2\) - x = y²

Answer 1

Ta có:

\(x+\left(-\frac{31}{12}\right)^2=\left(\frac{49}{12}\right)^2-x\)

\(\Rightarrow2x+\frac{961}{144}=\frac{2401}{144}\)

\(\Rightarrow2x=\frac{2401}{144}-\frac{961}{144}\)

\(\Rightarrow2x=\frac{1440}{144}\)

\(\Rightarrow2x=10\)

\(\Rightarrow x=5\)

Vậy \(x=5\)
