(180(n-2))/n =160

\frac{180 ( n - 2 )}{n} = 160

n = 18

Solution steps

\frac{180 ( n - 2 )}{n} = 160

Multiply both sides by

n

180 (n - 2) = 160 n

Expand

180 (n - 2) : 180 n - 360

180 n - 360 = 160 n

Move

360

to the right side

180 n = 160 n + 360

Move

160 n

to the left side

20 n = 360

Divide both sides by

20

n = 18

Verify Solutions

Find undefined (singularity) points:

n = 0

Combine undefined points with solutions:

n = 18

d, \frac{20}{d} = - 15

\frac{180 ( n - 2 )}{n} = 120

x = \frac{∣ x - 7 ∣}{x - 7}

\frac{8}{x} = \frac{10}{20}

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