Step-by-step explanation:
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 <em>i</em><em>s</em><em>,</em> because 2x-2+3x = 5x-2
because you combine like terms (2x+3x=5x) and -2 is left.
5 people - pay 135 each
15 people - pay x each
----------------------------------
5 : 15 = x : 135
15 x = 5 * 135
15 x = 675
x = 675 : 15
x = 45
