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:
$$19 x = 12 y + 16$$
Divide both parts of the equation by 19
We get the answer: x = 16/19 + 12*y/19
19*x-12*y = 16
Looking for similar summands in the left part:
-12*y + 19*x = 16
Move the summands with the other variables
from left part to right part, we given:
$$19 x = 12 y + 16$$
Divide both parts of the equation by 19
x = 16 + 12*y / (19)
We get the answer: x = 16/19 + 12*y/19

$$x_{1} = \frac{12 \operatorname{re}{\left(y\right)}}{19} + \frac{12 i \operatorname{im}{\left(y\right)}}{19} + \frac{16}{19}$$
x1 = 12*re(y)/19 + 12*i*im(y)/19 + 16/19
