\frac{2 x}{x + 2} + \frac{4}{x + 9} = 1

x = \frac{- 11 + 161}{2}, x = \frac{- 11 - 161}{2}

Decimal Notation

x = 0.84428 \dots, x = - 11.84428 \dots

Solution steps

\frac{2 x}{x + 2} + \frac{4}{x + 9} = 1

Multiply by LCM

2 x (x + 9) + 4 (x + 2) = (x + 2) (x + 9)

Solve

2 x (x + 9) + 4 (x + 2) = (x + 2) (x + 9) : x = \frac{- 11 + 161}{2}, x = \frac{- 11 - 161}{2}

x = \frac{- 11 + 161}{2}, x = \frac{- 11 - 161}{2}

Verify Solutions

Find undefined (singularity) points:

x = - 2, x = - 9

Combine undefined points with solutions:

x = \frac{- 11 + 161}{2}, x = \frac{- 11 - 161}{2}

\frac{2}{7 y} = \frac{11}{8}

6 = \frac{349.48}{349.48 - x} (5)

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

10045 = \frac{10175}{( 1 + r ) ^{1}}

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