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:
$$- 5 x = 19 - 6 y$$
Divide both parts of the equation by -5
We get the answer: x = -19/5 + 6*y/5
-5*x+6*y = 19
Looking for similar summands in the left part:
-5*x + 6*y = 19
Move the summands with the other variables
from left part to right part, we given:
$$- 5 x = 19 - 6 y$$
Divide both parts of the equation by -5
x = 19 - 6*y / (-5)
We get the answer: x = -19/5 + 6*y/5

$$x_{1} = \frac{6 \operatorname{re}{\left(y\right)}}{5} + \frac{6 i \operatorname{im}{\left(y\right)}}{5} - \frac{19}{5}$$
x1 = 6*re(y)/5 + 6*i*im(y)/5 - 19/5
