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:
$$- x = 7 y + 5$$
Divide both parts of the equation by -1
We get the answer: x = -5 - 7*y
-1*x-7*y = 5
Looking for similar summands in the left part:
-x - 7*y = 5
Move the summands with the other variables
from left part to right part, we given:
$$- x = 7 y + 5$$
Divide both parts of the equation by -1
x = 5 + 7*y / (-1)
We get the answer: x = -5 - 7*y

x1 = -5 - 7*re(y) - 7*I*im(y)
$$x_{1} = - 7 \operatorname{re}{\left(y\right)} - 7 i \operatorname{im}{\left(y\right)} - 5$$
x1 = -7*re(y) - 7*i*im(y) - 5
