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:
$$7 x = - 5 y - 17$$
Divide both parts of the equation by 7
We get the answer: x = -17/7 - 5*y/7
7*x+5*y = -17
Looking for similar summands in the left part:
5*y + 7*x = -17
Move the summands with the other variables
from left part to right part, we given:
$$7 x = - 5 y - 17$$
Divide both parts of the equation by 7
x = -17 - 5*y / (7)
We get the answer: x = -17/7 - 5*y/7

$$x_{1} = - \frac{5 \operatorname{re}{\left(y\right)}}{7} - \frac{5 i \operatorname{im}{\left(y\right)}}{7} - \frac{17}{7}$$
x1 = -5*re(y)/7 - 5*i*im(y)/7 - 17/7
