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
