(15)/y =3

Solution

\frac{15}{y} = 3

y = 5

Solution steps

\frac{15}{y} = 3

Multiply both sides by

y

15 = 3 y

Switch sides

3 y = 15

Divide both sides by

3

y = 5

Verify Solutions

Find undefined (singularity) points:

y = 0

Combine undefined points with solutions:

y = 5

\frac{( 8 - m ) \cdot ( m - 8 )}{m} = 16

f (a) = 8 - \frac{8}{a}, a = 8

8 π = \frac{2 π}{b}

\frac{3}{x - 2} = 4 - \frac{1}{3}

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