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:
$$15 x = - 11 y - 7$$
Divide both parts of the equation by 15
We get the answer: x = -7/15 - 11*y/15
15*x+11*y = -7
Looking for similar summands in the left part:
11*y + 15*x = -7
Move the summands with the other variables
from left part to right part, we given:
$$15 x = - 11 y - 7$$
Divide both parts of the equation by 15
x = -7 - 11*y / (15)
We get the answer: x = -7/15 - 11*y/15

$$x_{1} = - \frac{11 \operatorname{re}{\left(y\right)}}{15} - \frac{11 i \operatorname{im}{\left(y\right)}}{15} - \frac{7}{15}$$
x1 = -11*re(y)/15 - 11*i*im(y)/15 - 7/15
