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:
$$- 17 x = 8 y + 7$$
Divide both parts of the equation by -17
We get the answer: x = -7/17 - 8*y/17
-17*x-8*y = 7
Looking for similar summands in the left part:
-17*x - 8*y = 7
Move the summands with the other variables
from left part to right part, we given:
$$- 17 x = 8 y + 7$$
Divide both parts of the equation by -17
x = 7 + 8*y / (-17)
We get the answer: x = -7/17 - 8*y/17

$$x_{1} = - \frac{8 \operatorname{re}{\left(y\right)}}{17} - \frac{8 i \operatorname{im}{\left(y\right)}}{17} - \frac{7}{17}$$
x1 = -8*re(y)/17 - 8*i*im(y)/17 - 7/17
