3 x + \frac{3 π}{2} = \frac{π}{6} + 2 πn, 3 x + \frac{3 π}{2} = \frac{5 π}{6} + 2 πn

3 x + \frac{3 π}{2} = \frac{π}{6} + 2 πn, 3 x + \frac{3 π}{2} = \frac{5 π}{6} + 2 πn

Solve

3 x + \frac{3 π}{2} = \frac{π}{6} + 2 πn : x = \frac{2 πn}{3} - \frac{4 π}{9}

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

Move

\frac{3 π}{2}

to the right side

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

Subtract

\frac{3 π}{2}

from both sides

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

Simplify

Simplify

3 x + \frac{3 π}{2} - \frac{3 π}{2} : 3 x

3 x + \frac{3 π}{2} - \frac{3 π}{2}

Add similar elements:

\frac{3 π}{2} - \frac{3 π}{2} = 0

= 3 x

Simplify

\frac{π}{6} + 2 πn - \frac{3 π}{2} : 2 πn - \frac{4 π}{3}
