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:
$$19 x = 15 y + 15$$
Divide both parts of the equation by 19
We get the answer: x = 15/19 + 15*y/19
19*x-15*y = 15
Looking for similar summands in the left part:
-15*y + 19*x = 15
Move the summands with the other variables
from left part to right part, we given:
$$19 x = 15 y + 15$$
Divide both parts of the equation by 19
x = 15 + 15*y / (19)
We get the answer: x = 15/19 + 15*y/19

x1 = -- + -------- + ----------
19 19 19
$$x_{1} = \frac{15 \operatorname{re}{\left(y\right)}}{19} + \frac{15 i \operatorname{im}{\left(y\right)}}{19} + \frac{15}{19}$$
x1 = 15*re(y)/19 + 15*i*im(y)/19 + 15/19
