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:
$$- 16 x = 20 y + 6$$
Divide both parts of the equation by -16
We get the answer: x = -3/8 - 5*y/4
-16*x-20*y = 6
Looking for similar summands in the left part:
-20*y - 16*x = 6
Move the summands with the other variables
from left part to right part, we given:
$$- 16 x = 20 y + 6$$
Divide both parts of the equation by -16
x = 6 + 20*y / (-16)
We get the answer: x = -3/8 - 5*y/4

$$x_{1} = - \frac{5 \operatorname{re}{\left(y\right)}}{4} - \frac{5 i \operatorname{im}{\left(y\right)}}{4} - \frac{3}{8}$$
x1 = -5*re(y)/4 - 5*i*im(y)/4 - 3/8
