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:
$$- x = - 19 y - 10$$
Divide both parts of the equation by -1
We get the answer: x = 10 + 19*y
-1*x+19*y = -10
Looking for similar summands in the left part:
-x + 19*y = -10
Move the summands with the other variables
from left part to right part, we given:
$$- x = - 19 y - 10$$
Divide both parts of the equation by -1
x = -10 - 19*y / (-1)
We get the answer: x = 10 + 19*y

x1 = 10 + 19*re(y) + 19*I*im(y)
$$x_{1} = 19 \operatorname{re}{\left(y\right)} + 19 i \operatorname{im}{\left(y\right)} + 10$$
x1 = 19*re(y) + 19*i*im(y) + 10
