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:
$$- 5 x = 20 y - 7$$
Divide both parts of the equation by -5
We get the answer: x = 7/5 - 4*y
-5*x-20*y = -7
Looking for similar summands in the left part:
-20*y - 5*x = -7
Move the summands with the other variables
from left part to right part, we given:
$$- 5 x = 20 y - 7$$
Divide both parts of the equation by -5
x = -7 + 20*y / (-5)
We get the answer: x = 7/5 - 4*y

x1 = 7/5 - 4*re(y) - 4*I*im(y)
$$x_{1} = - 4 \operatorname{re}{\left(y\right)} - 4 i \operatorname{im}{\left(y\right)} + \frac{7}{5}$$
x1 = -4*re(y) - 4*i*im(y) + 7/5
