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

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