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:
$$- 20 x = 2 - 19 y$$
Divide both parts of the equation by -20
We get the answer: x = -1/10 + 19*y/20
-20*x+19*y = 2
Looking for similar summands in the left part:
-20*x + 19*y = 2
Move the summands with the other variables
from left part to right part, we given:
$$- 20 x = 2 - 19 y$$
Divide both parts of the equation by -20
x = 2 - 19*y / (-20)
We get the answer: x = -1/10 + 19*y/20

x1 = - -- + -------- + ----------
10 20 20
$$x_{1} = \frac{19 \operatorname{re}{\left(y\right)}}{20} + \frac{19 i \operatorname{im}{\left(y\right)}}{20} - \frac{1}{10}$$
x1 = 19*re(y)/20 + 19*i*im(y)/20 - 1/10
