9/x =3

Solution

\frac{9}{x} = 3

x = 3

Solution steps

\frac{9}{x} = 3

Multiply both sides by

x

9 = 3 x

Switch sides

3 x = 9

Divide both sides by

3

x = 3

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 3

\frac{1}{x + 3} + 4 = \frac{21}{x + 3}

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

m, a = \frac{f}{m}

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

\frac{5 x}{3 x - 6} = \frac{3}{2}
