2 x + \frac{π}{3} = 0 + 2 πn, 2 x + \frac{π}{3} = π + 2 πn

2 x + \frac{π}{3} = 0 + 2 πn, 2 x + \frac{π}{3} = π + 2 πn

Solve

2 x + \frac{π}{3} = 0 + 2 πn : x = πn - \frac{π}{6}

2 x + \frac{π}{3} = 0 + 2 πn

0 + 2 πn = 2 πn

2 x + \frac{π}{3} = 2 πn

Move

\frac{π}{3}

to the right side

2 x + \frac{π}{3} = 2 πn

Subtract

\frac{π}{3}

from both sides

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

Simplify

2 x = 2 πn - \frac{π}{3}

2 x = 2 πn - \frac{π}{3}

Divide both sides by

2

2 x = 2 πn - \frac{π}{3}

Divide both sides by

2

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

Simplify

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

Simplify

\frac{2 x}{2} : x

\frac{2 x}{2}

Divide the numbers:

\frac{2}{2} = 1

= x

Simplify

\frac{2 πn}{2} - \frac{\frac{π}{3}}{2} : πn - \frac{π}{6}

\frac{2 πn}{2} - \frac{\frac{π}{3}}{2}

\frac{2 πn}{2} = πn

\frac{2 πn}{2}

Divide the numbers:

\frac{2}{2} = 1

= πn

\frac{\frac{π}{3}}{2} = \frac{π}{6}

\frac{\frac{π}{3}}{2}

Apply the fraction rule:

\frac{\frac{b}{c}}{a} = \frac{b}{c \cdot a}

= \frac{π}{3 \cdot 2}

Multiply the numbers:

3 \cdot 2 = 6

= \frac{π}{6}

= πn - \frac{π}{6}

x = πn - \frac{π}{6}

x = πn - \frac{π}{6}

x = πn - \frac{π}{6}

Solve

2 x + \frac{π}{3} = π + 2 πn : x = πn + \frac{π}{2} - \frac{π}{6}

2 x + \frac{π}{3} = π + 2 πn

Move

\frac{π}{3}

to the right side

2 x + \frac{π}{3} = π + 2 πn

Subtract

\frac{π}{3}

from both sides

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

Simplify

2 x = π + 2 πn - \frac{π}{3}

2 x = π + 2 πn - \frac{π}{3}

Divide both sides by

2

2 x = π + 2 πn - \frac{π}{3}

Divide both sides by

2

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

Simplify

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

Simplify

\frac{2 x}{2} : x

\frac{2 x}{2}

Divide the numbers:

\frac{2}{2} = 1

= x

Simplify

\frac{π}{2} + \frac{2 πn}{2} - \frac{\frac{π}{3}}{2} : πn + \frac{π}{2} - \frac{π}{6}

\frac{π}{2} + \frac{2 πn}{2} - \frac{\frac{π}{3}}{2}

\frac{2 πn}{2} = πn

\frac{2 πn}{2}

Divide the numbers:

\frac{2}{2} = 1

= πn

\frac{\frac{π}{3}}{2} = \frac{π}{6}

\frac{\frac{π}{3}}{2}

Apply the fraction rule:

\frac{\frac{b}{c}}{a} = \frac{b}{c \cdot a}

= \frac{π}{3 \cdot 2}

Multiply the numbers:

3 \cdot 2 = 6

= \frac{π}{6}

= \frac{π}{2} + πn - \frac{π}{6}

Group like terms

= πn + \frac{π}{2} - \frac{π}{6}
