(y-7)/(y-9)= 3/4

\frac{y - 7}{y - 9} = \frac{3}{4}

y = 1

Solution steps

\frac{y - 7}{y - 9} = \frac{3}{4}

Cross multiply

4 y - 28 = 3 y - 27

Move

28

to the right side

4 y = 3 y + 1

Move

3 y

to the left side

y = 1

Verify Solutions

Find undefined (singularity) points:

y = 9

Combine undefined points with solutions:

y = 1

\frac{2}{2 x + 8} = \frac{3}{x + 2}

\frac{3}{5 - 2 x} = \frac{7}{2}

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

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

\frac{6}{x} - \frac{28}{x - 3} + 4 = 0
