Step-by-step explanation:
x= new books

(to help keep track)
12.50x + 5.50y or 12.50(16) + 5.50(25)
so 337.50 in revenue
Answer:
X = 0
Y = -3
Step-by-step explanation:
In this situation you would choose elimination.
-6x+y=-3
7x-y=3
---------------
x = 0
plug back in to find y
(-6)(0) + y = -3
0 + y = -3
y = -3
plug in to other equation for double check
7(0) - (-3) = 3
0 + 3 = 3
3 = 3
Hope this helps
