2/n = 4/10

\frac{2}{n} = \frac{4}{10}

n = 5

Solution steps

\frac{2}{n} = \frac{4}{10}

Cross multiply

20 = n \cdot 4

Switch sides

n \cdot 4 = 20

Divide both sides by

4

n = 5

Verify Solutions

Find undefined (singularity) points:

n = 0

Combine undefined points with solutions:

n = 5

\frac{9 x}{( x - 9 ) ( x - 4 )} = 3 x + 8

\frac{1}{5 x ^{3}} = \frac{8}{5}

2 = \frac{2}{x}

\frac{16 - x ^{2}}{2 x - 8} = 0

\frac{3 y + 9}{4 y - 5} = 6
