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:
$$13 x = 11 y + 16$$
Divide both parts of the equation by 13
We get the answer: x = 16/13 + 11*y/13
13*x-11*y = 16
Looking for similar summands in the left part:
-11*y + 13*x = 16
Move the summands with the other variables
from left part to right part, we given:
$$13 x = 11 y + 16$$
Divide both parts of the equation by 13
x = 16 + 11*y / (13)
We get the answer: x = 16/13 + 11*y/13

$$x_{1} = \frac{11 \operatorname{re}{\left(y\right)}}{13} + \frac{11 i \operatorname{im}{\left(y\right)}}{13} + \frac{16}{13}$$
x1 = 11*re(y)/13 + 11*i*im(y)/13 + 16/13
