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

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