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:
$$8 x = 17 - 19 y$$
Divide both parts of the equation by 8
We get the answer: x = 17/8 - 19*y/8
8*x+19*y = 17
Looking for similar summands in the left part:
8*x + 19*y = 17
Move the summands with the other variables
from left part to right part, we given:
$$8 x = 17 - 19 y$$
Divide both parts of the equation by 8
x = 17 - 19*y / (8)
We get the answer: x = 17/8 - 19*y/8

$$x_{1} = - \frac{19 \operatorname{re}{\left(y\right)}}{8} - \frac{19 i \operatorname{im}{\left(y\right)}}{8} + \frac{17}{8}$$
x1 = -19*re(y)/8 - 19*i*im(y)/8 + 17/8
