1/x+3=0

\frac{1}{x} + 3 = 0

x = - \frac{1}{3}

Solution steps

\frac{1}{x} + 3 = 0

Multiply both sides by

x

1 + 3 x = 0

Move

1

to the right side

3 x = - 1

Divide both sides by

3

x = - \frac{1}{3}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = - \frac{1}{3}

\frac{2 x}{x + 4} = 5 - \frac{8}{x + 4}

\frac{10}{2 a} = \frac{20}{4}

\frac{5 ( 2 x + 1 ) ^{2}}{4 x + 5} = 5 x - 1

\frac{2}{x - 2} = \frac{5}{x + 3}

y, x = \frac{y + 2}{y - 2}
