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:
$$- 17 x = 19 - 4 y$$
Divide both parts of the equation by -17
We get the answer: x = -19/17 + 4*y/17
-17*x+4*y = 19
Looking for similar summands in the left part:
-17*x + 4*y = 19
Move the summands with the other variables
from left part to right part, we given:
$$- 17 x = 19 - 4 y$$
Divide both parts of the equation by -17
x = 19 - 4*y / (-17)
We get the answer: x = -19/17 + 4*y/17

$$x_{1} = \frac{4 \operatorname{re}{\left(y\right)}}{17} + \frac{4 i \operatorname{im}{\left(y\right)}}{17} - \frac{19}{17}$$
x1 = 4*re(y)/17 + 4*i*im(y)/17 - 19/17
