(40)/y =8

Solution

\frac{40}{y} = 8

y = 5

Solution steps

\frac{40}{y} = 8

Multiply both sides by

y

40 = 8 y

Switch sides

8 y = 40

Divide both sides by

8

y = 5

Verify Solutions

Find undefined (singularity) points:

y = 0

Combine undefined points with solutions:

y = 5

\frac{( x + 5 ) !}{( x + 3 ) !} = 30

x, 2 = \frac{y - 10}{x - 5}

\frac{1}{y ^{2}} - y^{2} = 1

x + \frac{3}{x ^{2}} = 0

30 + (\frac{20 - 20}{x}) = 10
