The solution

You have entered [src]
4*x - 2*y = 0
$$4 x - 2 y = 0$$
Detail solution
Given the linear equation:
4*x-2*y = 0

Looking for similar summands in the left part:
-2*y + 4*x = 0

Move the summands with the other variables
from left part to right part, we given:
$$- 2 y = - 4 x$$
Divide both parts of the equation by -2
y = -4*x / (-2)

We get the answer: y = 2*x

sum
2*re(x) + 2*I*im(x)
$$2 \operatorname{re}{\left(x\right)} + 2 i \operatorname{im}{\left(x\right)}$$
=
2*re(x) + 2*I*im(x)
$$2 \operatorname{re}{\left(x\right)} + 2 i \operatorname{im}{\left(x\right)}$$
product
2*re(x) + 2*I*im(x)
$$2 \operatorname{re}{\left(x\right)} + 2 i \operatorname{im}{\left(x\right)}$$
=
2*re(x) + 2*I*im(x)
$$2 \operatorname{re}{\left(x\right)} + 2 i \operatorname{im}{\left(x\right)}$$
2*re(x) + 2*i*im(x)
Rapid solution [src]
y1 = 2*re(x) + 2*I*im(x)
$$y_{1} = 2 \operatorname{re}{\left(x\right)} + 2 i \operatorname{im}{\left(x\right)}$$
y1 = 2*re(x) + 2*i*im(x)
