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:
$$- 2 x = 4 y - 14$$
Divide both parts of the equation by -2
We get the answer: x = 7 - 2*y
-2*x-4*y = -14
Looking for similar summands in the left part:
-4*y - 2*x = -14
Move the summands with the other variables
from left part to right part, we given:
$$- 2 x = 4 y - 14$$
Divide both parts of the equation by -2
x = -14 + 4*y / (-2)
We get the answer: x = 7 - 2*y
Rapid solution

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