(12)/(y-3)=(15)/(y+3)

\frac{12}{y - 3} = \frac{15}{y + 3}

y = 27

Solution steps

\frac{12}{y - 3} = \frac{15}{y + 3}

Cross multiply

12 y + 36 = 15 y - 45

Move

36

to the right side

12 y = 15 y - 81

Move

15 y

to the left side

- 3 y = - 81

Divide both sides by

- 3

y = 27

Verify Solutions

Find undefined (singularity) points:

y = 3, y = - 3

Combine undefined points with solutions:

y = 27

7 - \frac{10}{x} = 2 + \frac{15}{x}

\frac{3 x - 7}{x + 3} = 0

\frac{3}{x} = \frac{x}{27}

\frac{4}{x} = \frac{3}{5}

\frac{2}{3 - x} - \frac{6}{8 - x} = 1
