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

y1 = 10 - 2*re(x) - 2*I*im(x)
$$y_{1} = - 2 \operatorname{re}{\left(x\right)} - 2 i \operatorname{im}{\left(x\right)} + 10$$
y1 = -2*re(x) - 2*i*im(x) + 10
