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:
$$14 x = - 9 y - 15$$
Divide both parts of the equation by 14
We get the answer: x = -15/14 - 9*y/14
14*x+9*y = -15
Looking for similar summands in the left part:
9*y + 14*x = -15
Move the summands with the other variables
from left part to right part, we given:
$$14 x = - 9 y - 15$$
Divide both parts of the equation by 14
x = -15 - 9*y / (14)
We get the answer: x = -15/14 - 9*y/14

$$x_{1} = - \frac{9 \operatorname{re}{\left(y\right)}}{14} - \frac{9 i \operatorname{im}{\left(y\right)}}{14} - \frac{15}{14}$$
x1 = -9*re(y)/14 - 9*i*im(y)/14 - 15/14
