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:
$$- x = 6 y - 20$$
Divide both parts of the equation by -1
We get the answer: x = 20 - 6*y
-1*x-6*y = -20
Looking for similar summands in the left part:
-x - 6*y = -20
Move the summands with the other variables
from left part to right part, we given:
$$- x = 6 y - 20$$
Divide both parts of the equation by -1
x = -20 + 6*y / (-1)
We get the answer: x = 20 - 6*y

x1 = 20 - 6*re(y) - 6*I*im(y)
$$x_{1} = - 6 \operatorname{re}{\left(y\right)} - 6 i \operatorname{im}{\left(y\right)} + 20$$
x1 = -6*re(y) - 6*i*im(y) + 20
