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:
$$- 5 x = 6 y - 1$$
Divide both parts of the equation by -5
We get the answer: x = 1/5 - 6*y/5
-5*x-6*y = -1
Looking for similar summands in the left part:
-6*y - 5*x = -1
Move the summands with the other variables
from left part to right part, we given:
$$- 5 x = 6 y - 1$$
Divide both parts of the equation by -5
x = -1 + 6*y / (-5)
We get the answer: x = 1/5 - 6*y/5

$$x_{1} = - \frac{6 \operatorname{re}{\left(y\right)}}{5} - \frac{6 i \operatorname{im}{\left(y\right)}}{5} + \frac{1}{5}$$
x1 = -6*re(y)/5 - 6*i*im(y)/5 + 1/5
