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:
$$- 14 x = 19 - 10 y$$
Divide both parts of the equation by -14
We get the answer: x = -19/14 + 5*y/7
-14*x+10*y = 19
Looking for similar summands in the left part:
-14*x + 10*y = 19
Move the summands with the other variables
from left part to right part, we given:
$$- 14 x = 19 - 10 y$$
Divide both parts of the equation by -14
x = 19 - 10*y / (-14)
We get the answer: x = -19/14 + 5*y/7

$$x_{1} = \frac{5 \operatorname{re}{\left(y\right)}}{7} + \frac{5 i \operatorname{im}{\left(y\right)}}{7} - \frac{19}{14}$$
x1 = 5*re(y)/7 + 5*i*im(y)/7 - 19/14
