24-\left(2x-\left(3-4-\left(-2x\right)\right)-1\right)
To find the opposite of 4-2x, find the opposite of each term.
24-\left(2x-\left(3-4+2x\right)-1\right)
The opposite of -2x is 2x.
24-\left(2x-\left(-1+2x\right)-1\right)
Subtract 4 from 3 to get -1.
24-\left(2x-\left(-1\right)-2x-1\right)
To find the opposite of -1+2x, find the opposite of each term.
24-\left(2x+1-2x-1\right)
The opposite of -1 is 1.
24-\left(1-1\right)
Combine 2x and -2x to get 0.
24-0
Subtract 1 from 1 to get 0.
24
Subtract 0 from 24 to get 24.
