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:
$$19 x = 3 y - 12$$
Divide both parts of the equation by 19
We get the answer: x = -12/19 + 3*y/19
19*x-3*y = -12
Looking for similar summands in the left part:
-3*y + 19*x = -12
Move the summands with the other variables
from left part to right part, we given:
$$19 x = 3 y - 12$$
Divide both parts of the equation by 19
x = -12 + 3*y / (19)
We get the answer: x = -12/19 + 3*y/19

x1 = - -- + ------- + ---------
19 19 19
$$x_{1} = \frac{3 \operatorname{re}{\left(y\right)}}{19} + \frac{3 i \operatorname{im}{\left(y\right)}}{19} - \frac{12}{19}$$
x1 = 3*re(y)/19 + 3*i*im(y)/19 - 12/19
