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

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