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:
$$- 10 x = 6 - 18 y$$
Divide both parts of the equation by -10
We get the answer: x = -3/5 + 9*y/5
-10*x+18*y = 6
Looking for similar summands in the left part:
-10*x + 18*y = 6
Move the summands with the other variables
from left part to right part, we given:
$$- 10 x = 6 - 18 y$$
Divide both parts of the equation by -10
x = 6 - 18*y / (-10)
We get the answer: x = -3/5 + 9*y/5

$$x_{1} = \frac{9 \operatorname{re}{\left(y\right)}}{5} + \frac{9 i \operatorname{im}{\left(y\right)}}{5} - \frac{3}{5}$$
x1 = 9*re(y)/5 + 9*i*im(y)/5 - 3/5
