In Problems 17-54, solve each system of equations. If the system has no solution, say that it is inconsisten
$\left\{\begin{array}{l}\frac{1}{x}+\frac{1}{y}=8 \\ \frac{3}{x}-\frac{5}{y}=0\end{array}\right.$

Key Concepts

System of Equations

A set of two or more equations with variables that are solved simultaneously. Solutions are the values that make all the equations true at the same time, and this concept applies whether the equations are linear, nonlinear, or involve more complex forms.

Rational Equations

These are equations that involve fractions whose numerators and/or denominators contain variables. Understanding how to work with rational equations includes mastering techniques to clear denominators and carefully checking for extraneous solutions caused by restrictions on the variable values.

Reciprocal Relationships

This concept involves equations where variables appear in the denominator, effectively as reciprocals. Recognizing such relationships can simplify the process of solving the equation by, for instance, substituting new variables to transform the problem into a more standard form.

Substitution and Elimination Methods

These are standard techniques used to solve systems of equations. In substitution, one equation is solved for a variable and then substituted into another, whereas elimination involves adding or subtracting equations to remove one variable, thereby reducing the system to a simpler form.

Inconsistency in Systems

An inconsistent system is one in which no solution exists because the equations contradict each other. Recognizing inconsistency is an essential part of solving systems, ensuring that the solver distinguishes between a unique solution, infinitely many solutions, or no solution at all.
