<span>x² + y² + 14x − 4y − 28 = 0
x² +14x +y² - 4y =28
x²+2*7x +7² -7² + y² - 2*2y +2² - 2² = 28
(x+7)² + (y-2)² -7²-2² =28
</span>(x+7)² + (y-2)²=28+49+4
(x+7)² + (y-2)² =81 is the answer.
Answer: An equation we can use to find the number of djembe drums you sold be

Step-by-step explanation:
Let price of maracas be m
Let the price of claves be c
Let the price of djembe drums be d
Number of maracas = 12 sets
Number of clavas = 6 sets
Number of djembe drums be xx
Total earned amount = $326
According to question,

Hence, an equation we can use to find the number of djembe drums you sold be

S = (5g -4y)/9
