(3x)/(x+1)=2

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

x = 2

Solution steps

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

Multiply both sides by

x + 1

3 x = 2 (x + 1)

Expand

2 (x + 1) : 2 x + 2

3 x = 2 x + 2

Move

2 x

to the left side

x = 2

Verify Solutions

Find undefined (singularity) points:

x = - 1

Combine undefined points with solutions:

x = 2

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

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

\frac{x}{x + 3} = \frac{4}{3}

\frac{x + 4}{x - 3} = 0

\frac{4}{m} = \frac{2}{9}
