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:
$$- 19 x = 20 - 19 y$$
Divide both parts of the equation by -19
We get the answer: x = -20/19 + y
-19*x+19*y = 20
Looking for similar summands in the left part:
-19*x + 19*y = 20
Move the summands with the other variables
from left part to right part, we given:
$$- 19 x = 20 - 19 y$$
Divide both parts of the equation by -19
x = 20 - 19*y / (-19)
We get the answer: x = -20/19 + y

x1 = - -- + I*im(y) + re(y)
19
$$x_{1} = \operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} - \frac{20}{19}$$
x1 = re(y) + i*im(y) - 20/19
