x+y=4 equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
x+y = 4
Looking for similar summands in the left part:
x + y = 4
Move the summands with the other variables
from left part to right part, we given:
$$x = 4 - y$$
We get the answer: x = 4 - y

$$- \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} + 4$$
$$- \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} + 4$$
$$- \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} + 4$$
$$- \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} + 4$$
$$x_{1} = - \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} + 4$$
x1 = -re(y) - i*im(y) + 4
