Hope this can help you! :)
answer is B. 2x−2+3x
5 x -2 = -10
A is not, because 2-5x = -5x+2
(nothing has changed but the order)
B is not, because 3-5+2x = 2x-2
because 3-5 = -2. so -2+2x can be rewritten as 2x-2.
C is not, because 5x-2x = 3x
because you combine like terms, and 5-2 is 3
D is, because 2x-2+3x = 5x-2
because you combine like terms (2x+3x=5x) and -2 is left.
The expression that is equivalent to the given expression is
