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:
$$6 x = 2 y + 20$$
Divide both parts of the equation by 6
We get the answer: x = 10/3 + y/3
6*x-2*y = 20
Looking for similar summands in the left part:
-2*y + 6*x = 20
Move the summands with the other variables
from left part to right part, we given:
$$6 x = 2 y + 20$$
Divide both parts of the equation by 6
x = 20 + 2*y / (6)
We get the answer: x = 10/3 + y/3

$$x_{1} = \frac{\operatorname{re}{\left(y\right)}}{3} + \frac{i \operatorname{im}{\left(y\right)}}{3} + \frac{10}{3}$$
x1 = re(y)/3 + i*im(y)/3 + 10/3
