3/(x+1)=2

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

x = \frac{1}{2}

Solution steps

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

Multiply both sides by

x + 1

3 = 2 (x + 1)

Switch sides

2 (x + 1) = 3

Divide both sides by

2

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

Move

1

to the right side

x = \frac{1}{2}

Verify Solutions

Find undefined (singularity) points:

x = - 1

Combine undefined points with solutions:

x = \frac{1}{2}

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

\frac{8}{( x - 2 ) ^{3}} = 0

\frac{1}{x - 3} + 2 = \frac{9}{x - 3}

\frac{x}{4} = \frac{16}{x}

\frac{4}{x} = \frac{10}{7.5}
