\frac{16 - x ^{2}}{4 - x} = 0

x = - 4

Solution steps

\frac{16 - x ^{2}}{4 - x} = 0

Simplify

\frac{16 - x ^{2}}{4 - x} : x + 4

x + 4 = 0

Move

4

to the right side

x = - 4

Verify Solutions

Find undefined (singularity) points:

x = 4

Combine undefined points with solutions:

x = - 4

\frac{6 x - 12}{3} + 4 = \frac{18}{x}

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

\frac{2}{x} = \frac{x}{5 x - 12}

\frac{x ^{2} + 4 x}{x + 2} = \frac{2 x}{3}

135 = \frac{180 ( x - 2 )}{x}
