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:
$$- 10 x = 19 y + 16$$
Divide both parts of the equation by -10
We get the answer: x = -8/5 - 19*y/10
-10*x-19*y = 16
Looking for similar summands in the left part:
-19*y - 10*x = 16
Move the summands with the other variables
from left part to right part, we given:
$$- 10 x = 19 y + 16$$
Divide both parts of the equation by -10
x = 16 + 19*y / (-10)
We get the answer: x = -8/5 - 19*y/10

$$x_{1} = - \frac{19 \operatorname{re}{\left(y\right)}}{10} - \frac{19 i \operatorname{im}{\left(y\right)}}{10} - \frac{8}{5}$$
x1 = -19*re(y)/10 - 19*i*im(y)/10 - 8/5
