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:
-8*y + 17*x = 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

x1 = -- + ------- + ---------
17 17 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
