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:
$$- 15 x = 13 - 17 y$$
Divide both parts of the equation by -15
We get the answer: x = -13/15 + 17*y/15
-15*x+17*y = 13
Looking for similar summands in the left part:
-15*x + 17*y = 13
Move the summands with the other variables
from left part to right part, we given:
$$- 15 x = 13 - 17 y$$
Divide both parts of the equation by -15
x = 13 - 17*y / (-15)
We get the answer: x = -13/15 + 17*y/15

x1 = - -- + -------- + ----------
15 15 15
$$x_{1} = \frac{17 \operatorname{re}{\left(y\right)}}{15} + \frac{17 i \operatorname{im}{\left(y\right)}}{15} - \frac{13}{15}$$
x1 = 17*re(y)/15 + 17*i*im(y)/15 - 13/15
