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

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