y= y/y

Solution

y = \frac{y}{y}

y = 1

Solution steps

y = \frac{y}{y}

Simplify

\frac{y}{y} : 1

y = 1

Verify Solutions

Find undefined (singularity) points:

y = 0

Combine undefined points with solutions:

y = 1

- 2 = \frac{10 - 20}{x}

\frac{x ^{2} - 6}{x - 3} = \frac{x}{x - 3}

\frac{1}{x} + \frac{1}{5 x} = 6

\frac{x}{3} + \frac{x - 1}{x} = \frac{7}{6}

\frac{4}{x} + \frac{2 ( x + 1 )}{3 ( x - 2 )} = 4
