(-2)/((x+2))=2

\frac{- 2}{( x + 2 )} = 2

x = - 3

Solution steps

\frac{- 2}{( x + 2 )} = 2

Simplify

\frac{- 2}{x + 2} : - \frac{2}{x + 2}

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

Multiply both sides by

x + 2

- 2 = 2 (x + 2)

Switch sides

2 (x + 2) = - 2

Divide both sides by

2

x + 2 = - 1

Move

2

to the right side

x = - 3

Verify Solutions

Find undefined (singularity) points:

x = - 2

Combine undefined points with solutions:

x = - 3

- \frac{1}{x} = - \frac{6}{x + 1}

\frac{1}{- 2} + \frac{3}{x + 3} = 0

\frac{4}{x} = a + b

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

u, Q = \frac{d}{1 - u}
