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

x1 = -7/2 - 7*re(y) - 7*I*im(y)
$$x_{1} = - 7 \operatorname{re}{\left(y\right)} - 7 i \operatorname{im}{\left(y\right)} - \frac{7}{2}$$
x1 = -7*re(y) - 7*i*im(y) - 7/2
