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:
$$- 2 x = 18 y + 10$$
Divide both parts of the equation by -2
We get the answer: x = -5 - 9*y
-2*x-18*y = 10
Looking for similar summands in the left part:
-18*y - 2*x = 10
Move the summands with the other variables
from left part to right part, we given:
$$- 2 x = 18 y + 10$$
Divide both parts of the equation by -2
x = 10 + 18*y / (-2)
We get the answer: x = -5 - 9*y
Rapid solution

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