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:
$$18 x = 12 - 14 y$$
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:
14*y + 18*x = 12
Move the summands with the other variables
from left part to right part, we given:
$$18 x = 12 - 14 y$$
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
