Answer:
I can't understand what you have written and what to find
Answer: 
Step-by-step explanation:
Let x be the price. 20% (0.20) 7.25% (0.0725)

5+7-4=6
6-4=2
I’ve created two equations with no solution
I’m pretty sure the 2nd one is the associate property and the 3rd one is the additive inverse property
Hope this helps :)
6x + 3 = -4y + 11
- 3 - 3
6x = -4y + 8
6x + 4y = -4y + 4y + 8
6x + 4y = 8
6x - 6x + 4y = -6x + 8
4y = -6x + 8
4 4
y = -1¹/₂x + 2
