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:
$$- 6 x = - 4 y - 14$$
Divide both parts of the equation by -6
We get the answer: x = 7/3 + 2*y/3
-6*x+4*y = -14
Looking for similar summands in the left part:
-6*x + 4*y = -14
Move the summands with the other variables
from left part to right part, we given:
$$- 6 x = - 4 y - 14$$
Divide both parts of the equation by -6
x = -14 - 4*y / (-6)
We get the answer: x = 7/3 + 2*y/3

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