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:
$$- 17 x = 7 y + 16$$
Divide both parts of the equation by -17
We get the answer: x = -16/17 - 7*y/17
-17*x-7*y = 16
Looking for similar summands in the left part:
-17*x - 7*y = 16
Move the summands with the other variables
from left part to right part, we given:
$$- 17 x = 7 y + 16$$
Divide both parts of the equation by -17
x = 16 + 7*y / (-17)
We get the answer: x = -16/17 - 7*y/17

$$x_{1} = - \frac{7 \operatorname{re}{\left(y\right)}}{17} - \frac{7 i \operatorname{im}{\left(y\right)}}{17} - \frac{16}{17}$$
x1 = -7*re(y)/17 - 7*i*im(y)/17 - 16/17
