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:
$$- 5 x = 10 - 19 y$$
Divide both parts of the equation by -5
We get the answer: x = -2 + 19*y/5
-5*x+19*y = 10
Looking for similar summands in the left part:
-5*x + 19*y = 10
Move the summands with the other variables
from left part to right part, we given:
$$- 5 x = 10 - 19 y$$
Divide both parts of the equation by -5
x = 10 - 19*y / (-5)
We get the answer: x = -2 + 19*y/5

x1 = -2 + -------- + ----------
5 5
$$x_{1} = \frac{19 \operatorname{re}{\left(y\right)}}{5} + \frac{19 i \operatorname{im}{\left(y\right)}}{5} - 2$$
x1 = 19*re(y)/5 + 19*i*im(y)/5 - 2
