No because the box has a fixed weight as the several books weighing said pounds would most likely to be use as the x in this equation.
Its in the tens place so the unit value is 30
X - 2y = - 9
7x + 2y = 1
x - 2y = - 9
(+)
7x + 2y = 1
___________
8x = - 8
x = - 1
- 1 - 2y = - 9
2y = 8
y = 4

Answer:
2
Step-by-step explanation:
Total costs = 4 + (3 * 2) + 5 + 15
Total costs = 4 + 6 + 5 + 15
Total costs = $ 30
Substituting values we have:
Total change = 32 - 30
Total change = 2 $
The inequality would be 34 > 2 x 3, if I'm correct. I'm not to sure on the graph part though , sorry.
