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:
$$7 x = y - 7$$
Divide both parts of the equation by 7
We get the answer: x = -1 + y/7
7*x-1*y = -7
Looking for similar summands in the left part:
-y + 7*x = -7
Move the summands with the other variables
from left part to right part, we given:
$$7 x = y - 7$$
Divide both parts of the equation by 7
x = -7 + y / (7)
We get the answer: x = -1 + y/7

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