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:
$$8 x = 8 y + 7$$
Divide both parts of the equation by 8
We get the answer: x = 7/8 + y
8*x-8*y = 7
Looking for similar summands in the left part:
-8*y + 8*x = 7
Move the summands with the other variables
from left part to right part, we given:
$$8 x = 8 y + 7$$
Divide both parts of the equation by 8
x = 7 + 8*y / (8)
We get the answer: x = 7/8 + y

x1 = 7/8 + I*im(y) + re(y)
$$x_{1} = \operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} + \frac{7}{8}$$
x1 = re(y) + i*im(y) + 7/8
