Detail solution
Given the equation
$$- \frac{3 x}{2} + \sin{\left(x + y \right)} = \frac{1}{10}$$
- this is the simplest trigonometric equation
This equation is transformed to
$$x + y = 2 \pi n + \operatorname{asin}{\left(\frac{3 x}{2} + \frac{1}{10} \right)}$$
$$x + y = 2 \pi n - \operatorname{asin}{\left(\frac{3 x}{2} + \frac{1}{10} \right)} + \pi$$
Or
$$x + y = 2 \pi n + \operatorname{asin}{\left(\frac{3 x}{2} + \frac{1}{10} \right)}$$
$$x + y = 2 \pi n - \operatorname{asin}{\left(\frac{3 x}{2} + \frac{1}{10} \right)} + \pi$$
, where n - is a integer
Move
$$x$$
to right part of the equation
with the opposite sign, in total:
$$y = 2 \pi n - x + \operatorname{asin}{\left(\frac{3 x}{2} + \frac{1}{10} \right)}$$
$$y = 2 \pi n - x - \operatorname{asin}{\left(\frac{3 x}{2} + \frac{1}{10} \right)} + \pi$$
