-(6x)/(x-7)-9= 3/(x-7)

- \frac{6 x}{x - 7} - 9 = \frac{3}{x - 7}

x = 4

Solution steps

- \frac{6 x}{x - 7} - 9 = \frac{3}{x - 7}

Multiply both sides by

x - 7

- 6 x - 9 (x - 7) = 3

Expand

- 9 (x - 7) : - 9 x + 63

- 6 x - 9 x + 63 = 3

Add similar elements:

- 6 x - 9 x = - 15 x

- 15 x + 63 = 3

Move

63

to the right side

- 15 x = - 60

Divide both sides by

- 15

x = 4

Verify Solutions

Find undefined (singularity) points:

x = 7

Combine undefined points with solutions:

x = 4

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

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

\frac{1}{2 x} + \frac{1}{4 x} = \frac{3}{12}

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

\frac{7 x - 4}{x + 2} - \frac{4}{7 x} = 7
