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:
$$14 x = 19 - 7 y$$
Divide both parts of the equation by 14
We get the answer: x = 19/14 - y/2
14*x+7*y = 19
Looking for similar summands in the left part:
7*y + 14*x = 19
Move the summands with the other variables
from left part to right part, we given:
$$14 x = 19 - 7 y$$
Divide both parts of the equation by 14
x = 19 - 7*y / (14)
We get the answer: x = 19/14 - y/2

$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{2} - \frac{i \operatorname{im}{\left(y\right)}}{2} + \frac{19}{14}$$
x1 = -re(y)/2 - i*im(y)/2 + 19/14
