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

x1 = -2 + I*im(y) + re(y)
$$x_{1} = \operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} - 2$$
x1 = re(y) + i*im(y) - 2
