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:
$$2 x = 13 - 18 y$$
Divide both parts of the equation by 2
We get the answer: x = 13/2 - 9*y
2*x+18*y = 13
Looking for similar summands in the left part:
2*x + 18*y = 13
Move the summands with the other variables
from left part to right part, we given:
$$2 x = 13 - 18 y$$
Divide both parts of the equation by 2
x = 13 - 18*y / (2)
We get the answer: x = 13/2 - 9*y

x1 = 13/2 - 9*re(y) - 9*I*im(y)
$$x_{1} = - 9 \operatorname{re}{\left(y\right)} - 9 i \operatorname{im}{\left(y\right)} + \frac{13}{2}$$
x1 = -9*re(y) - 9*i*im(y) + 13/2
