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:
$$- 8 x = 19 - 10 y$$
Divide both parts of the equation by -8
We get the answer: x = -19/8 + 5*y/4
-8*x+10*y = 19
Looking for similar summands in the left part:
-8*x + 10*y = 19
Move the summands with the other variables
from left part to right part, we given:
$$- 8 x = 19 - 10 y$$
Divide both parts of the equation by -8
x = 19 - 10*y / (-8)
We get the answer: x = -19/8 + 5*y/4

$$x_{1} = \frac{5 \operatorname{re}{\left(y\right)}}{4} + \frac{5 i \operatorname{im}{\left(y\right)}}{4} - \frac{19}{8}$$
x1 = 5*re(y)/4 + 5*i*im(y)/4 - 19/8
