Probably the first one "multiply equation A by -4". In order to cancel them out out multiply the first equation by negative 4 and then you add both equations once you add both equations -4+4=0 so they cancel out.
First, solve for x
x + y = 6
+
2x - y = 9
——————
3x = 15
x = 5
then just substitute that into one of the equations
(5) + y = 6
y = 1
then make into an ordered pair (x,y)
(5, 1)
Answer:
A = 5
B = 9
Step-by-step explanation:
This was very simple!
Nancy needs at least 15 boxes of travoprost but she only has 10. To find out how many she needs, we subtract 15 from 10 to get 5 boxes
Nancy also needs at least 12 boxes of latanoprost but she only has 3. To find out how many she needs, we subtract 12 from 3 to get 9 boxes
Therefore A = 5 boxes; B = 9 boxes

50 might be the answer because 12÷6=2 so I just multiplied 15×2 and that equaled my answer, 50
