(x+3)/7 = 3/(x-1)

\frac{x + 3}{7} = \frac{3}{x - 1}

x = 4, x = - 6

Solution steps

\frac{x + 3}{7} = \frac{3}{x - 1}

Cross multiply

(x + 3) (x - 1) = 21

Solve

(x + 3) (x - 1) = 21 : x = 4, x = - 6

x = 4, x = - 6

Verify Solutions

Find undefined (singularity) points:

x = 1

Combine undefined points with solutions:

x = 4, x = - 6

\frac{3 x ^{2} - 4}{x} = 3 (x - 4)

y, \frac{x}{y} = x

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

x^{2} + \frac{1}{x} = 0, x > 0

r, S = \frac{a}{a - r}
