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

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

x = - 3, x = 1

Solution steps

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

Cross multiply

x \cdot 4 = - (x - 3) (x + 1)

Solve

x \cdot 4 = - (x - 3) (x + 1) : x = - 3, x = 1

x = - 3, x = 1

Verify Solutions

Find undefined (singularity) points:

x = 3

Combine undefined points with solutions:

x = - 3, x = 1

0.488 = 1 - (\frac{20}{20 + x})^{3}

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

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

- \frac{1}{x} + \frac{2}{45 x} = 43

\frac{x - 5}{x ^{2} - 3 x - 10} = 2
