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

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