1/(x+2)=3

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

x = - \frac{5}{3}

Decimal Notation

x = - 1.66666 \dots

Solution steps

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

Multiply both sides by

x + 2

1 = 3 (x + 2)

Switch sides

3 (x + 2) = 1

Divide both sides by

3

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

Move

2

to the right side

x = - \frac{5}{3}

Verify Solutions

Find undefined (singularity) points:

x = - 2

Combine undefined points with solutions:

x = - \frac{5}{3}

2 (\frac{( n + 1 ) !}{n !}) = 40

\frac{x + 1}{4} = \frac{5}{x}

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

1 - \frac{64}{x ^{2}} = 0

\frac{( a x + b )}{c x + d} = 2
