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:
$$18 x = 19 y + 10$$
Divide both parts of the equation by 18
We get the answer: x = 5/9 + 19*y/18
18*x-19*y = 10
Looking for similar summands in the left part:
-19*y + 18*x = 10
Move the summands with the other variables
from left part to right part, we given:
$$18 x = 19 y + 10$$
Divide both parts of the equation by 18
x = 10 + 19*y / (18)
We get the answer: x = 5/9 + 19*y/18

5 19*re(y) 19*I*im(y)
x1 = - + -------- + ----------
9 18 18
$$x_{1} = \frac{19 \operatorname{re}{\left(y\right)}}{18} + \frac{19 i \operatorname{im}{\left(y\right)}}{18} + \frac{5}{9}$$
x1 = 19*re(y)/18 + 19*i*im(y)/18 + 5/9
