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:
$$17 x = 7 y + 15$$
Divide both parts of the equation by 17
We get the answer: x = 15/17 + 7*y/17
17*x-7*y = 15
Looking for similar summands in the left part:
-7*y + 17*x = 15
Move the summands with the other variables
from left part to right part, we given:
$$17 x = 7 y + 15$$
Divide both parts of the equation by 17
x = 15 + 7*y / (17)
We get the answer: x = 15/17 + 7*y/17

x1 = -- + ------- + ---------
17 17 17
$$x_{1} = \frac{7 \operatorname{re}{\left(y\right)}}{17} + \frac{7 i \operatorname{im}{\left(y\right)}}{17} + \frac{15}{17}$$
x1 = 7*re(y)/17 + 7*i*im(y)/17 + 15/17
