find all real numbers x and y that satisfy

-2x-1-2yi=4x-5i
I think the first step is rewrite with constant complex on one side.
-2x-2yi-4x=1-5i
now I'm lost

To solve the equation -2x - 1 - 2yi = 4x - 5i, you're correct in rewriting it with the constant complex on one side. However, there was a small error in your calculation. It should be:

-2x - 2yi - 4x = 1 - 5i

Next, combine like terms:

-6x - 2yi = 1 - 5i

To get the real part and the imaginary part on separate sides, separate the equation into two parts:

-6x = 1 (1)
-2yi = -5i (2)

Now, let's solve equation (1) for x:

-6x = 1

Divide both sides by -6:

x = 1/(-6)

Simplifying further:

x = -1/6

Now, let's solve equation (2) for y:

-2yi = -5i

Divide both sides by -2i:

y = (-5i) / (-2i)

-i and -i can be canceled out, resulting in:

y = 5/2

So, the solution to the given equation is:

x = -1/6
y = 5/2

Hence, the real numbers x and y that satisfy the equation -2x - 1 - 2yi = 4x - 5i are x = -1/6 and y = 5/2.
