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:
$$5 x = - 20 y - 3$$
Divide both parts of the equation by 5
We get the answer: x = -3/5 - 4*y
5*x+20*y = -3
Looking for similar summands in the left part:
5*x + 20*y = -3
Move the summands with the other variables
from left part to right part, we given:
$$5 x = - 20 y - 3$$
Divide both parts of the equation by 5
x = -3 - 20*y / (5)
We get the answer: x = -3/5 - 4*y

x1 = -3/5 - 4*re(y) - 4*I*im(y)
$$x_{1} = - 4 \operatorname{re}{\left(y\right)} - 4 i \operatorname{im}{\left(y\right)} - \frac{3}{5}$$
x1 = -4*re(y) - 4*i*im(y) - 3/5
