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:
$$19 x = 19 y + 20$$
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*y + 19*x = 20
Move the summands with the other variables
from left part to right part, we given:
$$19 x = 19 y + 20$$
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
