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

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