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:
$$5 x = 10 - 3 y$$
Divide both parts of the equation by 5
We get the answer: x = 2 - 3*y/5
5*x+3*y = 10
Looking for similar summands in the left part:
3*y + 5*x = 10
Move the summands with the other variables
from left part to right part, we given:
$$5 x = 10 - 3 y$$
Divide both parts of the equation by 5
x = 10 - 3*y / (5)
We get the answer: x = 2 - 3*y/5

$$x_{1} = - \frac{3 \operatorname{re}{\left(y\right)}}{5} - \frac{3 i \operatorname{im}{\left(y\right)}}{5} + 2$$
x1 = -3*re(y)/5 - 3*i*im(y)/5 + 2
