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:
$$2 x = 17 y - 13$$
Divide both parts of the equation by 2
We get the answer: x = -13/2 + 17*y/2
2*x-17*y = -13
Looking for similar summands in the left part:
-17*y + 2*x = -13
Move the summands with the other variables
from left part to right part, we given:
$$2 x = 17 y - 13$$
Divide both parts of the equation by 2
x = -13 + 17*y / (2)
We get the answer: x = -13/2 + 17*y/2

$$x_{1} = \frac{17 \operatorname{re}{\left(y\right)}}{2} + \frac{17 i \operatorname{im}{\left(y\right)}}{2} - \frac{13}{2}$$
x1 = 17*re(y)/2 + 17*i*im(y)/2 - 13/2
