Sanji paid 25 for two scarves which were different prices when she got home she could not find the receipt she remember that one

laila [671]

Answer:

The answer is x = 14 the more expensive scarf

Step-by-step explanation:

x + y = 25

3 + y + y = 25 (x = 3 + y)

3 + 2y = 25

2y = 25 - 3

2y = 22

y = 22/2

y = 11

x = 3 + y

x = 3 + 11

x = 14 (the more expensive scarf)

(x,y) ; (14,11)
