(-2)/(2x+1)= 1/2

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

x = - \frac{5}{2}

Decimal Notation

x = - 2.5

Solution steps

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

Cross multiply

- 4 = 2 x + 1

Switch sides

2 x + 1 = - 4

Move

1

to the right side

2 x = - 5

Divide both sides by

2

x = - \frac{5}{2}

Verify Solutions

Find undefined (singularity) points:

x = - \frac{1}{2}

Combine undefined points with solutions:

x = - \frac{5}{2}

\frac{2}{x + 2} = 5 x - 1

\frac{2}{r} = \frac{12}{18}

y, \frac{x - 3}{y} = x

\frac{6}{y} = \frac{5}{2 y} - 7

\frac{3}{1 - c} = 4
