1/(3x)+1/(4x)=720

\frac{1}{3 x} + \frac{1}{4 x} = 720

x = \frac{7}{8640}

Decimal Notation

x = 0.00081 \dots

Solution steps

\frac{1}{3 x} + \frac{1}{4 x} = 720

Multiply both sides by

x

\frac{1}{3} + \frac{1}{4} = 720 x

Switch sides

720 x = \frac{1}{3} + \frac{1}{4}

Simplify

\frac{1}{3} + \frac{1}{4} : \frac{7}{12}

720 x = \frac{7}{12}

Divide both sides by

720

x = \frac{7}{8640}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{7}{8640}

\frac{7}{x + 1} = \frac{4 x - 6}{2 x - 3}

\frac{21}{a + 2} = \frac{3}{a - 1}

\frac{x + 2}{x ^{2} - 3 x} = 0

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

x - \frac{3 x + 5}{x + 1} = \frac{2 x}{x + 1}
