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:
$$- 16 x = 17 y + 4$$
Divide both parts of the equation by -16
We get the answer: x = -1/4 - 17*y/16
-16*x-17*y = 4
Looking for similar summands in the left part:
-17*y - 16*x = 4
Move the summands with the other variables
from left part to right part, we given:
$$- 16 x = 17 y + 4$$
Divide both parts of the equation by -16
x = 4 + 17*y / (-16)
We get the answer: x = -1/4 - 17*y/16

$$x_{1} = - \frac{17 \operatorname{re}{\left(y\right)}}{16} - \frac{17 i \operatorname{im}{\left(y\right)}}{16} - \frac{1}{4}$$
x1 = -17*re(y)/16 - 17*i*im(y)/16 - 1/4
