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:
$$- 17 x = 18 y + 5$$
Divide both parts of the equation by -17
We get the answer: x = -5/17 - 18*y/17
-17*x-18*y = 5
Looking for similar summands in the left part:
-18*y - 17*x = 5
Move the summands with the other variables
from left part to right part, we given:
$$- 17 x = 18 y + 5$$
Divide both parts of the equation by -17
x = 5 + 18*y / (-17)
We get the answer: x = -5/17 - 18*y/17

$$x_{1} = - \frac{18 \operatorname{re}{\left(y\right)}}{17} - \frac{18 i \operatorname{im}{\left(y\right)}}{17} - \frac{5}{17}$$
x1 = -18*re(y)/17 - 18*i*im(y)/17 - 5/17
