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:
$$6 x = 9 y + 18$$
Divide both parts of the equation by 6
We get the answer: x = 3 + 3*y/2
6*x-9*y = 18
Looking for similar summands in the left part:
-9*y + 6*x = 18
Move the summands with the other variables
from left part to right part, we given:
$$6 x = 9 y + 18$$
Divide both parts of the equation by 6
x = 18 + 9*y / (6)
We get the answer: x = 3 + 3*y/2

$$x_{1} = \frac{3 \operatorname{re}{\left(y\right)}}{2} + \frac{3 i \operatorname{im}{\left(y\right)}}{2} + 3$$
x1 = 3*re(y)/2 + 3*i*im(y)/2 + 3
