x + 3 0^{\circ} = 3 0^{\circ} + 36 0^{\circ} n, x + 3 0^{\circ} = 15 0^{\circ} + 36 0^{\circ} n

x + 3 0^{\circ} = 3 0^{\circ} + 36 0^{\circ} n, x + 3 0^{\circ} = 15 0^{\circ} + 36 0^{\circ} n

Solve

x + 3 0^{\circ} = 3 0^{\circ} + 36 0^{\circ} n : x = 36 0^{\circ} n

x + 3 0^{\circ} = 3 0^{\circ} + 36 0^{\circ} n

Subtract

3 0^{\circ}

from both sides

x + 3 0^{\circ} - 3 0^{\circ} = 3 0^{\circ} + 36 0^{\circ} n - 3 0^{\circ}

Simplify

x = 36 0^{\circ} n

Solve

x + 3 0^{\circ} = 15 0^{\circ} + 36 0^{\circ} n : x = 36 0^{\circ} n + 12 0^{\circ}

x + 3 0^{\circ} = 15 0^{\circ} + 36 0^{\circ} n

Move

3 0^{\circ}

to the right side

x + 3 0^{\circ} = 15 0^{\circ} + 36 0^{\circ} n

Subtract

3 0^{\circ}

from both sides

x + 3 0^{\circ} - 3 0^{\circ} = 15 0^{\circ} + 36 0^{\circ} n - 3 0^{\circ}

Simplify

x + 3 0^{\circ} - 3 0^{\circ} = 15 0^{\circ} + 36 0^{\circ} n - 3 0^{\circ}

Simplify

x + 3 0^{\circ} - 3 0^{\circ} : x

x + 3 0^{\circ} - 3 0^{\circ}

Add similar elements:

3 0^{\circ} - 3 0^{\circ} = 0

= x

Simplify

15 0^{\circ} + 36 0^{\circ} n - 3 0^{\circ} : 36 0^{\circ} n + 12 0^{\circ}

15 0^{\circ} + 36 0^{\circ} n - 3 0^{\circ}

Group like terms

= 36 0^{\circ} n - 3 0^{\circ} + 15 0^{\circ}

Combine the fractions

- 3 0^{\circ} + 15 0^{\circ} : 12 0^{\circ}

Apply rule

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

= \frac{- 18 0 ^{\circ} + 90 0 ^{\circ}}{6}

Add similar elements:

- 18 0^{\circ} + 90 0^{\circ} = 72 0^{\circ}

= 12 0^{\circ}

Cancel the common factor:

2

= 12 0^{\circ}

= 36 0^{\circ} n + 12 0^{\circ}

x = 36 0^{\circ} n + 12 0^{\circ}

x = 36 0^{\circ} n + 12 0^{\circ}

x = 36 0^{\circ} n + 12 0^{\circ}

x = 36 0^{\circ} n, x = 36 0^{\circ} n + 12 0^{\circ}
