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:
-7*x + 5*y = -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

x1 = -- + ------- + ---------
7 7 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
