A. 2x+y=25; x+y=20
x represents cheese wafers and y represents chocolate wafers.
B. I will choose elimination since there is y and y. I can multiply one equation by -1 to get y and -y, which cancels out.
2x+y=25
-x-y=-20
Add equations
x=5
Plug x in
5+y=20
y=15
Final answer: 5 cheese wafers, 15 chocolate wafers

Answer:
(3,4)
Step-by-step explanation:
x+y=7, where y=4, so therefore make x the subject and substitute y=4
x=7-y
x=7-4
x=3
therefore x=3, y=4.
