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:
$$- 18 x = 14 y + 12$$
Divide both parts of the equation by -18
We get the answer: x = -2/3 - 7*y/9
-18*x-14*y = 12
Looking for similar summands in the left part:
-18*x - 14*y = 12
Move the summands with the other variables
from left part to right part, we given:
$$- 18 x = 14 y + 12$$
Divide both parts of the equation by -18
x = 12 + 14*y / (-18)
We get the answer: x = -2/3 - 7*y/9

$$x_{1} = - \frac{7 \operatorname{re}{\left(y\right)}}{9} - \frac{7 i \operatorname{im}{\left(y\right)}}{9} - \frac{2}{3}$$
x1 = -7*re(y)/9 - 7*i*im(y)/9 - 2/3
