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:
$$- x = 1 - 20 y$$
Divide both parts of the equation by -1
We get the answer: x = -1 + 20*y
-1*x+20*y = 1
Looking for similar summands in the left part:
-x + 20*y = 1
Move the summands with the other variables
from left part to right part, we given:
$$- x = 1 - 20 y$$
Divide both parts of the equation by -1
x = 1 - 20*y / (-1)
We get the answer: x = -1 + 20*y

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