1/x+4=0

\frac{1}{x} + 4 = 0

x = - \frac{1}{4}

Solution steps

\frac{1}{x} + 4 = 0

Multiply both sides by

x

1 + 4 x = 0

Move

1

4 x = - 1

Divide both sides by

4

x = - \frac{1}{4}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = - \frac{1}{4}

\frac{a}{x} = \frac{b}{c}

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

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

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

\frac{6}{2 k - 6} = 3
