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:
$$- 19 x = 14 - 11 y$$
Divide both parts of the equation by -19
We get the answer: x = -14/19 + 11*y/19
-19*x+11*y = 14
Looking for similar summands in the left part:
-19*x + 11*y = 14
Move the summands with the other variables
from left part to right part, we given:
$$- 19 x = 14 - 11 y$$
Divide both parts of the equation by -19
x = 14 - 11*y / (-19)
We get the answer: x = -14/19 + 11*y/19

$$x_{1} = \frac{11 \operatorname{re}{\left(y\right)}}{19} + \frac{11 i \operatorname{im}{\left(y\right)}}{19} - \frac{14}{19}$$
x1 = 11*re(y)/19 + 11*i*im(y)/19 - 14/19
