y= 1/y

y = \frac{1}{y}

y = 1, y = - 1

Solution steps

y = \frac{1}{y}

Multiply both sides by

y

y^{2} = 1

Solve

y^{2} = 1 : y = 1, y = - 1

y = 1, y = - 1

Verify Solutions

Find undefined (singularity) points:

y = 0

Combine undefined points with solutions:

y = 1, y = - 1

c = \frac{20 t}{t ^{2} + 4}

4 x^{2} + x^{- 1} - 3 = 0

\frac{x}{x + 4} + \frac{4}{x + 4} = - 2

4 - \frac{8000}{x ^{2}} = 0

\frac{2 x}{3} + \frac{3}{2 x} = 1
