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:
$$10 x = 2 - 3 y$$
Divide both parts of the equation by 10
We get the answer: x = 1/5 - 3*y/10
10*x+3*y = 2
Looking for similar summands in the left part:
3*y + 10*x = 2
Move the summands with the other variables
from left part to right part, we given:
$$10 x = 2 - 3 y$$
Divide both parts of the equation by 10
x = 2 - 3*y / (10)
We get the answer: x = 1/5 - 3*y/10

$$x_{1} = - \frac{3 \operatorname{re}{\left(y\right)}}{10} - \frac{3 i \operatorname{im}{\left(y\right)}}{10} + \frac{1}{5}$$
x1 = -3*re(y)/10 - 3*i*im(y)/10 + 1/5
