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:
$$15 x = 19 y + 2$$
Divide both parts of the equation by 15
We get the answer: x = 2/15 + 19*y/15
15*x-19*y = 2
Looking for similar summands in the left part:
-19*y + 15*x = 2
Move the summands with the other variables
from left part to right part, we given:
$$15 x = 19 y + 2$$
Divide both parts of the equation by 15
x = 2 + 19*y / (15)
We get the answer: x = 2/15 + 19*y/15

2 19*re(y) 19*I*im(y)
x1 = -- + -------- + ----------
15 15 15
$$x_{1} = \frac{19 \operatorname{re}{\left(y\right)}}{15} + \frac{19 i \operatorname{im}{\left(y\right)}}{15} + \frac{2}{15}$$
x1 = 19*re(y)/15 + 19*i*im(y)/15 + 2/15
