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:
$$- 3 x = 2 y$$
Divide both parts of the equation by -3
We get the answer: x = -2*y/3
-3*x-2*y = 0
Looking for similar summands in the left part:
-3*x - 2*y = 0
Move the summands with the other variables
from left part to right part, we given:
$$- 3 x = 2 y$$
Divide both parts of the equation by -3
x = 2*y / (-3)
We get the answer: x = -2*y/3

2*re(y) 2*I*im(y)
x1 = - ------- - ---------
3 3
$$x_{1} = - \frac{2 \operatorname{re}{\left(y\right)}}{3} - \frac{2 i \operatorname{im}{\left(y\right)}}{3}$$
x1 = -2*re(y)/3 - 2*i*im(y)/3
