5+x/(x+2)=1

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

x = - \frac{8}{5}

Decimal Notation

x = - 1.6

Solution steps

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

Move

5

to the right side

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

Multiply both sides by

x + 2

x = - 4 (x + 2)

Expand

- 4 (x + 2) : - 4 x - 8

x = - 4 x - 8

Move

4 x

to the left side

5 x = - 8

Divide both sides by

5

x = - \frac{8}{5}

Verify Solutions

Find undefined (singularity) points:

x = - 2

Combine undefined points with solutions:

x = - \frac{8}{5}

s, b = \frac{f}{s - v}

1 - \frac{3 x}{x - 8} = x

4.2596 = \frac{4 π ^{2}}{x}

3 x + \frac{6}{x + 1} = 8

\frac{x + 2}{5 x} = \frac{x - 3}{4 x}
