(a-1)/4 = 8/(a+3)

\frac{a - 1}{4} = \frac{8}{a + 3}

a = 5, a = - 7

Solution steps

\frac{a - 1}{4} = \frac{8}{a + 3}

Cross multiply

(a - 1) (a + 3) = 32

Solve

(a - 1) (a + 3) = 32 : a = 5, a = - 7

a = 5, a = - 7

Verify Solutions

Find undefined (singularity) points:

a = - 3

Combine undefined points with solutions:

a = 5, a = - 7

\frac{4}{x} = \frac{16}{5 x} + 4

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

\frac{5}{6} = \frac{13}{x + 1}

0.2 = \frac{x ^{2}}{75 - x}

\frac{3}{x} = 0
