\frac{\frac{y}{xy}+\frac{2x}{xy}}{\frac{7}{x}-\frac{1}{y^{2}}}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x and y is xy. Multiply \frac{1}{x} times \frac{y}{y}. Multiply \frac{2}{y} times \frac{x}{x}.
\frac{\frac{y+2x}{xy}}{\frac{7}{x}-\frac{1}{y^{2}}}
Since \frac{y}{xy} and \frac{2x}{xy} have the same denominator, add them by adding their numerators.
\frac{\frac{y+2x}{xy}}{\frac{7y^{2}}{xy^{2}}-\frac{x}{xy^{2}}}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x and y^{2} is xy^{2}. Multiply \frac{7}{x} times \frac{y^{2}}{y^{2}}. Multiply \frac{1}{y^{2}} times \frac{x}{x}.
\frac{\frac{y+2x}{xy}}{\frac{7y^{2}-x}{xy^{2}}}
Since \frac{7y^{2}}{xy^{2}} and \frac{x}{xy^{2}} have the same denominator, subtract them by subtracting their numerators.
\frac{\left(y+2x\right)xy^{2}}{xy\left(7y^{2}-x\right)}
Divide \frac{y+2x}{xy} by \frac{7y^{2}-x}{xy^{2}} by multiplying \frac{y+2x}{xy} by the reciprocal of \frac{7y^{2}-x}{xy^{2}}.
\frac{y\left(2x+y\right)}{-x+7y^{2}}
Cancel out xy in both numerator and denominator.
\frac{2yx+y^{2}}{-x+7y^{2}}
Use the distributive property to multiply y by 2x+y.
\frac{\frac{y}{xy}+\frac{2x}{xy}}{\frac{7}{x}-\frac{1}{y^{2}}}
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x and y is xy. Multiply \frac{1}{x} times \frac{y}{y}. Multiply \frac{2}{y} times \frac{x}{x}.
\frac{\frac{y+2x}{xy}}{\frac{7}{x}-\frac{1}{y^{2}}}
Since \frac{y}{xy} and \frac{2x}{xy} have the same denominator, add them by adding their numerators.

\frac{\frac{y+2x}{xy}}{\frac{7y^{2}-x}{xy^{2}}}
Since \frac{7y^{2}}{xy^{2}} and \frac{x}{xy^{2}} have the same denominator, subtract them by subtracting their numerators.
\frac{\left(y+2x\right)xy^{2}}{xy\left(7y^{2}-x\right)}
Divide \frac{y+2x}{xy} by \frac{7y^{2}-x}{xy^{2}} by multiplying \frac{y+2x}{xy} by the reciprocal of \frac{7y^{2}-x}{xy^{2}}.
\frac{y\left(2x+y\right)}{-x+7y^{2}}
Cancel out xy in both numerator and denominator.
\frac{2yx+y^{2}}{-x+7y^{2}}
Use the distributive property to multiply y by 2x+y.
