Add \(\frac{49}{64}\) to both sides.
\[{x}^{2}=\frac{49}{64}\]
Take the square root of both sides.
\[x=\pm \sqrt{\frac{49}{64}}\]
Simplify \(\sqrt{\frac{49}{64}}\) to \(\frac{\sqrt{49}}{\sqrt{64}}\).
\[x=\pm \frac{\sqrt{49}}{\sqrt{64}}\]
Since \(7\times 7=49\), the square root of \(49\) is \(7\).
\[x=\pm \frac{7}{\sqrt{64}}\]
Since \(8\times 8=64\), the square root of \(64\) is \(8\).
\[x=\pm \frac{7}{8}\]
