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:
$$- 20 x = 13 y + 15$$
Divide both parts of the equation by -20
We get the answer: x = -3/4 - 13*y/20
-20*x-13*y = 15
Looking for similar summands in the left part:
-20*x - 13*y = 15
Move the summands with the other variables
from left part to right part, we given:
$$- 20 x = 13 y + 15$$
Divide both parts of the equation by -20
x = 15 + 13*y / (-20)
We get the answer: x = -3/4 - 13*y/20

$$x_{1} = - \frac{13 \operatorname{re}{\left(y\right)}}{20} - \frac{13 i \operatorname{im}{\left(y\right)}}{20} - \frac{3}{4}$$
x1 = -13*re(y)/20 - 13*i*im(y)/20 - 3/4
