Simplify
Detail solution
Given the linear equation:
x-y = 7

Looking for similar summands in the left part:
x - y = 7

Move the summands with the other variables
from left part to right part, we given:
x=y+7x = y + 7
We get the answer: x = 7 + y

=
7 + I*im(y) + re(y)
re⁡(y)+iim⁡(y)+7\operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} + 7 
7 + i*im(y) + re(y)
Rapid solution [src] 
x1 = 7 + I*im(y) + re(y)
x1=re⁡(y)+iim⁡(y)+7x_{1} = \operatorname{re}{\left(y\right)} + i \operatorname{im}{\left(y\right)} + 7 
x1 = re(y) + i*im(y) + 7
