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:
$$- 17 x = - 2 y - 4$$
Divide both parts of the equation by -17
We get the answer: x = 4/17 + 2*y/17
-17*x+2*y = -4
Looking for similar summands in the left part:
-17*x + 2*y = -4
Move the summands with the other variables
from left part to right part, we given:
$$- 17 x = - 2 y - 4$$
Divide both parts of the equation by -17
x = -4 - 2*y / (-17)
We get the answer: x = 4/17 + 2*y/17

$$x_{1} = \frac{2 \operatorname{re}{\left(y\right)}}{17} + \frac{2 i \operatorname{im}{\left(y\right)}}{17} + \frac{4}{17}$$
x1 = 2*re(y)/17 + 2*i*im(y)/17 + 4/17
