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:
$$x = 10 - 2 y$$
We get the answer: x = 10 - 2*y
1*x+2*y = 10
Looking for similar summands in the left part:
x + 2*y = 10
Move the summands with the other variables
from left part to right part, we given:
$$x = 10 - 2 y$$
We get the answer: x = 10 - 2*y

x1 = 10 - 2*re(y) - 2*I*im(y)
$$x_{1} = - 2 \operatorname{re}{\left(y\right)} - 2 i \operatorname{im}{\left(y\right)} + 10$$
x1 = -2*re(y) - 2*i*im(y) + 10
