y-2/y =1

y - \frac{2}{y} = 1

y = 2, y = - 1

Solution steps

y - \frac{2}{y} = 1

Multiply both sides by

y

y^{2} - 2 = y

Solve

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

y = 2, y = - 1

Verify Solutions

Find undefined (singularity) points:

y = 0

Combine undefined points with solutions:

y = 2, y = - 1
