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:
$$- 9 x = 14 - 2 y$$
Divide both parts of the equation by -9
We get the answer: x = -14/9 + 2*y/9
-9*x+2*y = 14
Looking for similar summands in the left part:
-9*x + 2*y = 14
Move the summands with the other variables
from left part to right part, we given:
$$- 9 x = 14 - 2 y$$
Divide both parts of the equation by -9
x = 14 - 2*y / (-9)
We get the answer: x = -14/9 + 2*y/9

$$x_{1} = \frac{2 \operatorname{re}{\left(y\right)}}{9} + \frac{2 i \operatorname{im}{\left(y\right)}}{9} - \frac{14}{9}$$
x1 = 2*re(y)/9 + 2*i*im(y)/9 - 14/9
