1 necklace = $8.50
1 pair of earrings = $3.75
8.50+3.75 = 12.25
19.75 - 12.25 = 7.5
7.5 / 3.75 = 2
in total ava bought 3 pairs of earrings

ANSWER: 
GOOD LUCK, I hope this helped!
Answer:
Part a) We should try to eliminate the y's because the coefficients are the same
Part b) The solution is the point (6,-9)
Step-by-step explanation:
Part a) Which variable pair should we try to eliminate?
we have
----> equation 1
----> equation 2
Solve by elimination
We should try to eliminate the y's because the coefficients are the same
Part b) What is the solution to the system?
Multiply equation 2 by -1 both sides

-----> equation 3
Adds equation 1 and equation 3

Find the value of y
