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:
$$- 10 x = 18 y + 15$$
Divide both parts of the equation by -10
We get the answer: x = -3/2 - 9*y/5
-10*x-18*y = 15
Looking for similar summands in the left part:
-18*y - 10*x = 15
Move the summands with the other variables
from left part to right part, we given:
$$- 10 x = 18 y + 15$$
Divide both parts of the equation by -10
x = 15 + 18*y / (-10)
We get the answer: x = -3/2 - 9*y/5

$$x_{1} = - \frac{9 \operatorname{re}{\left(y\right)}}{5} - \frac{9 i \operatorname{im}{\left(y\right)}}{5} - \frac{3}{2}$$
x1 = -9*re(y)/5 - 9*i*im(y)/5 - 3/2
