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

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