((12)/x+1)(x-3)=9

(\frac{12}{x} + 1) (x - 3) = 9

x = 6, x = - 6

Solution steps

(\frac{12}{x} + 1) (x - 3) = 9

Simplify

(\frac{12}{x} + 1) (x - 3) : x - \frac{36}{x} + 9

x - \frac{36}{x} + 9 = 9

Multiply both sides by

x

x^{2} - 36 + 9 x = 9 x

Solve

x^{2} - 36 + 9 x = 9 x : x = 6, x = - 6

x = 6, x = - 6

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 6, x = - 6

\frac{7 x + 3}{7 x - 9} = \frac{9}{4}

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

1 - \frac{1}{( x - 1 ) ^{2}} = 0

\frac{x + 8}{x + 9} = \frac{4}{5}

\frac{- 2}{5 y} = 4
