2/8 =(n+4)/(n-4)

\frac{2}{8} = \frac{n + 4}{n - 4}

n = - \frac{20}{3}

Decimal Notation

n = - 6.66666 \dots

Solution steps

\frac{2}{8} = \frac{n + 4}{n - 4}

Cross multiply

2 n - 8 = 8 n + 32

Move

8

to the right side

2 n = 8 n + 40

Move

8 n

to the left side

- 6 n = 40

Divide both sides by

- 6

n = - \frac{20}{3}

Verify Solutions

Find undefined (singularity) points:

n = 4

Combine undefined points with solutions:

n = - \frac{20}{3}

x, F = - \frac{k}{x ^{2}}

C, \frac{1 + TC}{C} = 1 + T

\frac{3 x + 5}{( x - 1 ) ( x ^{4} + 7 )} = 0
