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

$$x_{1} = \frac{14 \operatorname{re}{\left(y\right)}}{3} + \frac{14 i \operatorname{im}{\left(y\right)}}{3} + \frac{14}{3}$$
x1 = 14*re(y)/3 + 14*i*im(y)/3 + 14/3
