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:
$$9 x = - 14 y - 5$$
Divide both parts of the equation by 9
We get the answer: x = -5/9 - 14*y/9
9*x+14*y = -5
Looking for similar summands in the left part:
9*x + 14*y = -5
Move the summands with the other variables
from left part to right part, we given:
$$9 x = - 14 y - 5$$
Divide both parts of the equation by 9
x = -5 - 14*y / (9)
We get the answer: x = -5/9 - 14*y/9

$$x_{1} = - \frac{14 \operatorname{re}{\left(y\right)}}{9} - \frac{14 i \operatorname{im}{\left(y\right)}}{9} - \frac{5}{9}$$
x1 = -14*re(y)/9 - 14*i*im(y)/9 - 5/9
