3 π x = 0 + 2 πn, 3 π x = π + 2 πn

3 π x = 0 + 2 πn, 3 π x = π + 2 πn

Solve

3 π x = 0 + 2 πn : x = \frac{2 n}{3}

3 π x = 0 + 2 πn

0 + 2 πn = 2 πn

3 π x = 2 πn

Divide both sides by

3 π

3 π x = 2 πn

Divide both sides by

3 π

\frac{3 π x}{3 π} = \frac{2 πn}{3 π}

Simplify

x = \frac{2 n}{3}

x = \frac{2 n}{3}

Solve

3 π x = π + 2 πn : x = \frac{1}{3} + \frac{2 n}{3}

3 π x = π + 2 πn

Divide both sides by

3 π

3 π x = π + 2 πn

Divide both sides by

3 π

\frac{3 π x}{3 π} = \frac{π}{3 π} + \frac{2 πn}{3 π}

Simplify

\frac{3 π x}{3 π} = \frac{π}{3 π} + \frac{2 πn}{3 π}

Simplify

\frac{3 π x}{3 π} : x

\frac{3 π x}{3 π}

Divide the numbers:

\frac{3}{3} = 1

= \frac{π x}{π}

Cancel the common factor:

π

= x

Simplify

\frac{π}{3 π} + \frac{2 πn}{3 π} : \frac{1}{3} + \frac{2 n}{3}

\frac{π}{3 π} + \frac{2 πn}{3 π}

Cancel

\frac{π}{3 π} : \frac{1}{3}

\frac{π}{3 π}

Cancel the common factor:

π

= \frac{1}{3}

= \frac{1}{3} + \frac{2 πn}{3 π}

Cancel

\frac{2 πn}{3 π} : \frac{2 n}{3}

\frac{2 πn}{3 π}

Cancel the common factor:

π

= \frac{2 n}{3}

= \frac{1}{3} + \frac{2 n}{3}

x = \frac{1}{3} + \frac{2 n}{3}

x = \frac{1}{3} + \frac{2 n}{3}

x = \frac{1}{3} + \frac{2 n}{3}

x = \frac{2 n}{3}, x = \frac{1}{3} + \frac{2 n}{3}
