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:
$$- x = 10 - 2 y$$
Divide both parts of the equation by -1
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:
$$- x = 10 - 2 y$$
Divide both parts of the equation by -1
x = 10 - 2*y / (-1)
We get the answer: x = -10 + 2*y
Rapid solution

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
