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:
$$6 x = 19 y - 18$$
Divide both parts of the equation by 6
We get the answer: x = -3 + 19*y/6
6*x-19*y = -18
Looking for similar summands in the left part:
-19*y + 6*x = -18
Move the summands with the other variables
from left part to right part, we given:
$$6 x = 19 y - 18$$
Divide both parts of the equation by 6
x = -18 + 19*y / (6)
We get the answer: x = -3 + 19*y/6

6 6
$$x_{1} = \frac{19 \operatorname{re}{\left(y\right)}}{6} + \frac{19 i \operatorname{im}{\left(y\right)}}{6} - 3$$
x1 = 19*re(y)/6 + 19*i*im(y)/6 - 3
