Answer:
Yes, the expressions are equivalent.
Step-by-step explanation:
Notice that -2 is defined as in additive inverse of 2, that is, 2 + -2 = 0.
and substracting 2 from 2 is also equal to zero, that is, 2 - 2 = 0.
Thus 2-2 = 2+ -2, implying -2 = + -2. Consequently, -5 + -2 = -5 -2

Answer:
x = (66.50 - 4y) / 3
Step-by-step explanation:
Given that:
Amount had = $70
Change collected = $3.50
Total amount spent = $(70 - 3.50) = $66.50
Total amount used for purchasing prawn and fish:
Kg of fish = 4
Kg of prawn = 3
1 kg prawn will cost, x
If 1 kg of fish = y
(Total amount spent - cost of 4 kg fish) / Number of kg of prawn
($66.50 - 4y) / 3
x = (66.50 - 4y) / 3
