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:
$$14 x = 14 - 4 y$$
Divide both parts of the equation by 14
We get the answer: x = 1 - 2*y/7
14*x+4*y = 14
Looking for similar summands in the left part:
4*y + 14*x = 14
Move the summands with the other variables
from left part to right part, we given:
$$14 x = 14 - 4 y$$
Divide both parts of the equation by 14
x = 14 - 4*y / (14)
We get the answer: x = 1 - 2*y/7

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