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:
$$11 x = 10 y - 3$$
Divide both parts of the equation by 11
We get the answer: x = -3/11 + 10*y/11
11*x-10*y = -3
Looking for similar summands in the left part:
-10*y + 11*x = -3
Move the summands with the other variables
from left part to right part, we given:
$$11 x = 10 y - 3$$
Divide both parts of the equation by 11
x = -3 + 10*y / (11)
We get the answer: x = -3/11 + 10*y/11

$$x_{1} = \frac{10 \operatorname{re}{\left(y\right)}}{11} + \frac{10 i \operatorname{im}{\left(y\right)}}{11} - \frac{3}{11}$$
x1 = 10*re(y)/11 + 10*i*im(y)/11 - 3/11
