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:
$$15 x = - 12 y - 11$$
Divide both parts of the equation by 15
We get the answer: x = -11/15 - 4*y/5
15*x+12*y = -11
Looking for similar summands in the left part:
12*y + 15*x = -11
Move the summands with the other variables
from left part to right part, we given:
$$15 x = - 12 y - 11$$
Divide both parts of the equation by 15
x = -11 - 12*y / (15)
We get the answer: x = -11/15 - 4*y/5

$$x_{1} = - \frac{4 \operatorname{re}{\left(y\right)}}{5} - \frac{4 i \operatorname{im}{\left(y\right)}}{5} - \frac{11}{15}$$
x1 = -4*re(y)/5 - 4*i*im(y)/5 - 11/15
