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
