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:
$$- 15 x = 12 y + 14$$
Divide both parts of the equation by -15
We get the answer: x = -14/15 - 4*y/5
-15*x-12*y = 14
Looking for similar summands in the left part:
-15*x - 12*y = 14
Move the summands with the other variables
from left part to right part, we given:
$$- 15 x = 12 y + 14$$
Divide both parts of the equation by -15
x = 14 + 12*y / (-15)
We get the answer: x = -14/15 - 4*y/5

$$x_{1} = - \frac{4 \operatorname{re}{\left(y\right)}}{5} - \frac{4 i \operatorname{im}{\left(y\right)}}{5} - \frac{14}{15}$$
x1 = -4*re(y)/5 - 4*i*im(y)/5 - 14/15
