\frac{\frac{25}{5}-\frac{7}{5}}{\frac{24}{7}\sqrt{2}}=\frac{x}{5+\frac{7}{5}}
Convert 5 to fraction \frac{25}{5}.
\frac{\frac{25-7}{5}}{\frac{24}{7}\sqrt{2}}=\frac{x}{5+\frac{7}{5}}
Since \frac{25}{5} and \frac{7}{5} have the same denominator, subtract them by subtracting their numerators.
\frac{\frac{18}{5}}{\frac{24}{7}\sqrt{2}}=\frac{x}{5+\frac{7}{5}}
Subtract 7 from 25 to get 18.
\frac{18}{5\times \frac{24}{7}\sqrt{2}}=\frac{x}{5+\frac{7}{5}}
Express \frac{\frac{18}{5}}{\frac{24}{7}\sqrt{2}} as a single fraction.
\frac{18\sqrt{2}}{5\times \frac{24}{7}\left(\sqrt{2}\right)^{2}}=\frac{x}{5+\frac{7}{5}}
Rationalize the denominator of \frac{18}{5\times \frac{24}{7}\sqrt{2}} by multiplying numerator and denominator by \sqrt{2}.
\frac{18\sqrt{2}}{5\times \frac{24}{7}\times 2}=\frac{x}{5+\frac{7}{5}}
The square of \sqrt{2} is 2.
\frac{9\sqrt{2}}{\frac{24}{7}\times 5}=\frac{x}{5+\frac{7}{5}}
Cancel out 2 in both numerator and denominator.
\frac{9\sqrt{2}}{\frac{24\times 5}{7}}=\frac{x}{5+\frac{7}{5}}
Express \frac{24}{7}\times 5 as a single fraction.
\frac{9\sqrt{2}}{\frac{120}{7}}=\frac{x}{5+\frac{7}{5}}
Multiply 24 and 5 to get 120.
\frac{21}{40}\sqrt{2}=\frac{x}{5+\frac{7}{5}}
Divide 9\sqrt{2} by \frac{120}{7} to get \frac{21}{40}\sqrt{2}.
\frac{21}{40}\sqrt{2}=\frac{x}{\frac{25}{5}+\frac{7}{5}}
Convert 5 to fraction \frac{25}{5}.
\frac{21}{40}\sqrt{2}=\frac{x}{\frac{25+7}{5}}
Since \frac{25}{5} and \frac{7}{5} have the same denominator, add them by adding their numerators.
\frac{21}{40}\sqrt{2}=\frac{x}{\frac{32}{5}}
Add 25 and 7 to get 32.
\frac{x}{\frac{32}{5}}=\frac{21}{40}\sqrt{2}
Swap sides so that all variable terms are on the left hand side.
\frac{5}{32}x=\frac{21\sqrt{2}}{40}
The equation is in standard form.
\frac{\frac{5}{32}x}{\frac{5}{32}}=\frac{21\sqrt{2}}{\frac{5}{32}\times 40}
Divide both sides of the equation by \frac{5}{32}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{21\sqrt{2}}{\frac{5}{32}\times 40}
Dividing by \frac{5}{32} undoes the multiplication by \frac{5}{32}.
x=\frac{84\sqrt{2}}{25}
Divide \frac{21\sqrt{2}}{40} by \frac{5}{32} by multiplying \frac{21\sqrt{2}}{40} by the reciprocal of \frac{5}{32}.
