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:
$$4 x = 5 - 2 y$$
Divide both parts of the equation by 4
We get the answer: x = 5/4 - y/2
4*x+2*y = 5
Looking for similar summands in the left part:
2*y + 4*x = 5
Move the summands with the other variables
from left part to right part, we given:
$$4 x = 5 - 2 y$$
Divide both parts of the equation by 4
x = 5 - 2*y / (4)
We get the answer: x = 5/4 - y/2

$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{2} - \frac{i \operatorname{im}{\left(y\right)}}{2} + \frac{5}{4}$$
x1 = -re(y)/2 - i*im(y)/2 + 5/4
