The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$- 2 x = 15 y - 1$$
Divide both parts of the equation by -2
We get the answer: x = 1/2 - 15*y/2
-2*x-15*y = -1
Looking for similar summands in the left part:
-15*y - 2*x = -1
Move the summands with the other variables
from left part to right part, we given:
$$- 2 x = 15 y - 1$$
Divide both parts of the equation by -2
x = -1 + 15*y / (-2)
We get the answer: x = 1/2 - 15*y/2

$$x_{1} = - \frac{15 \operatorname{re}{\left(y\right)}}{2} - \frac{15 i \operatorname{im}{\left(y\right)}}{2} + \frac{1}{2}$$
