2x+1=(15)/x

2 x + 1 = \frac{15}{x}

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

Decimal Notation

x = 2.5, x = - 3

Solution steps

2 x + 1 = \frac{15}{x}

Multiply both sides by

x

2 x^{2} + x = 15

Solve

2 x^{2} + x = 15 : x = \frac{5}{2}, x = - 3

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

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

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

\frac{11}{x + 1} = \frac{3}{x - 1}

10 = \frac{100}{10 x - 120}

\frac{32}{24} = \frac{60}{x}

\frac{2 - 3 x}{2 + 5 x} = 1

\frac{5}{x - 1} = \frac{x}{x - 1}
