2 x^{2} + 2 = 5 x : x = 2, x = \frac{1}{2}

x = 2, x = \frac{1}{2}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 2, x = \frac{1}{2}

\frac{8}{6} = \frac{4}{x - 7}

\frac{3 y - 1}{2 y + 4} = \frac{4}{5}

\frac{2 x}{1 + x ^{2}} = 0

\frac{6}{3 c} = \frac{2}{3}

\frac{∣ x - 2 ∣}{x - 2} = 1
