x - y + 2 = 0
(x−y)+2=0\left(x - y\right) + 2 = 0
Simplify
Detail solution
Given the linear equation:
x-y+2 = 0

Looking for similar summands in the left part:
2 + x - y = 0

Move free summands (without x)
from left part to right part, we given:
x−y=−2x - y = -2
Move the summands with the other variables
from left part to right part, we given:
x=y+−2x = y + -2
We get the answer: x = -2 + y

re⁡(y)+iim⁡(y)−2\operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} - 2 
=
-2 + I*im(y) + re(y)
re⁡(y)+iim⁡(y)−2\operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} - 2 
-2 + i*im(y) + re(y)
Rapid solution [src] 
x1 = -2 + I*im(y) + re(y)
x1=re⁡(y)+iim⁡(y)−2x_{1} = \operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} - 2 
x1 = re(y) + i*im(y) - 2
