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:
11*y + 19*x = 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
