3/x+4/(x+1)=2

\frac{3}{x} + \frac{4}{x + 1} = 2

x = 3, x = - \frac{1}{2}

Decimal Notation

x = 3, x = - 0.5

Solution steps

\frac{3}{x} + \frac{4}{x + 1} = 2

Multiply by LCM

3 (x + 1) + 4 x = 2 x (x + 1)

Solve

3 (x + 1) + 4 x = 2 x (x + 1) : x = 3, x = - \frac{1}{2}

x = 3, x = - \frac{1}{2}

Verify Solutions

Find undefined (singularity) points:

x = 0, x = - 1

Combine undefined points with solutions:

x = 3, x = - \frac{1}{2}
