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:
$$17 x = 19 y + 1$$
Divide both parts of the equation by 17
We get the answer: x = 1/17 + 19*y/17
17*x-19*y = 1
Looking for similar summands in the left part:
-19*y + 17*x = 1
Move the summands with the other variables
from left part to right part, we given:
$$17 x = 19 y + 1$$
Divide both parts of the equation by 17
x = 1 + 19*y / (17)
We get the answer: x = 1/17 + 19*y/17

x1 = -- + -------- + ----------
17 17 17
$$x_{1} = \frac{19 \operatorname{re}{\left(y\right)}}{17} + \frac{19 i \operatorname{im}{\left(y\right)}}{17} + \frac{1}{17}$$
x1 = 19*re(y)/17 + 19*i*im(y)/17 + 1/17
