(5k+7)/(k-1)=3k+2

\frac{5 k + 7}{k - 1} = 3 k + 2

k = 3, k = - 1

Solution steps

\frac{5 k + 7}{k - 1} = 3 k + 2

Multiply both sides by

k - 1

5 k + 7 = 3 k (k - 1) + 2 (k - 1)

Solve

5 k + 7 = 3 k (k - 1) + 2 (k - 1) : k = 3, k = - 1

k = 3, k = - 1

Verify Solutions

Find undefined (singularity) points:

k = 1

Combine undefined points with solutions:

k = 3, k = - 1

\frac{6}{x + 2} = \frac{3}{x - 4}

0 = \frac{3 x - 4}{2 x + 6}

0 = x - 5 + \frac{4}{x}

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

\frac{32}{x} = 15
