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:
$ 154
Step-by-step explanation
Let the value of suitcase=x
x × 4.5% = 6.93 (converted the question into equation)
x ×
= 6.93 (converted the percentage into fraction)
x = 6.93 x
(took reciprocal of 4.5/100 after moving it to the other side of the equation)
x =
(multiplied the values)
x = 154 $ (simplified the fraction)
