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

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