\frac{θ}{3} + \frac{3 π}{4} = \frac{π}{6} + πn

\frac{θ}{3} + \frac{3 π}{4} = \frac{π}{6} + πn

Solve

\frac{θ}{3} + \frac{3 π}{4} = \frac{π}{6} + πn : θ = 3 πn - \frac{7 π}{4}

\frac{θ}{3} + \frac{3 π}{4} = \frac{π}{6} + πn

Move

\frac{3 π}{4}

to the right side

\frac{θ}{3} + \frac{3 π}{4} = \frac{π}{6} + πn

Subtract

\frac{3 π}{4}

from both sides

\frac{θ}{3} + \frac{3 π}{4} - \frac{3 π}{4} = \frac{π}{6} + πn - \frac{3 π}{4}

Simplify

\frac{θ}{3} + \frac{3 π}{4} - \frac{3 π}{4} = \frac{π}{6} + πn - \frac{3 π}{4}

Simplify

\frac{θ}{3} + \frac{3 π}{4} - \frac{3 π}{4} : \frac{θ}{3}

\frac{θ}{3} + \frac{3 π}{4} - \frac{3 π}{4}

Add similar elements:

\frac{3 π}{4} - \frac{3 π}{4} = 0

= \frac{θ}{3}

Simplify

\frac{π}{6} + πn - \frac{3 π}{4} : πn - \frac{7 π}{12}

\frac{π}{6} + πn - \frac{3 π}{4}

For

\frac{π}{6} :

multiply the denominator and numerator by

2

\frac{π}{6} = \frac{π 2}{6 \cdot 2} = \frac{π 2}{12}

For

\frac{3 π}{4} :

multiply the denominator and numerator by

\frac{3 π}{4} = \frac{3 π 3}{4 \cdot 3} = \frac{9 π}{12}

= \frac{π 2}{12} - \frac{9 π}{12}

Since the denominators are equal, combine the fractions:

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

= \frac{π 2 - 9 π}{12}

Add similar elements:

2 π - 9 π = - 7 π

= \frac{- 7 π}{12}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= πn - \frac{7 π}{12}

\frac{θ}{3} = πn - \frac{7 π}{12}

\frac{θ}{3} = πn - \frac{7 π}{12}

\frac{θ}{3} = πn - \frac{7 π}{12}

Multiply both sides by

3

\frac{θ}{3} = πn - \frac{7 π}{12}

Multiply both sides by

Simplify

3 πn - 3 \cdot \frac{7 π}{12} : 3 πn - \frac{7 π}{4}

3 πn - 3 \cdot \frac{7 π}{12}

3 \cdot \frac{7 π}{12} = \frac{7 π}{4}

3 \cdot \frac{7 π}{12}

Multiply fractions:

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

= \frac{7 π 3}{12}

Multiply the numbers:

7 \cdot 3 = 21

= \frac{21 π}{12}

Cancel the common factor:

3

= \frac{7 π}{4}

= 3 πn - \frac{7 π}{4}

θ = 3 πn - \frac{7 π}{4}

θ = 3 πn - \frac{7 π}{4}

θ = 3 πn - \frac{7 π}{4}

θ = 3 πn - \frac{7 π}{4}
