The correct answer: x=-7/2
Hope this help!!!
Price of one citron = 5 units
Price of one fragrant = 5/7 units = 0.71 units
Further explanation:
Let x be the price of one citron and
y be the price of one fragrant
Then according to given statement
10x+7y = 55 Eqn 1
7x+10y = 64 Eqn 2
Multiplying equation 1 by 7
![7(10x+7y) = 7(55)\\70x+49y=385](https://tex.z-dn.net/?f=7%2810x%2B7y%29%20%3D%207%2855%29%5C%5C70x%2B49y%3D385)
This will be equation 3.
Multiplying equation 2 by 10
![10(7x+10y) = 10(64)\\70x+100y=640](https://tex.z-dn.net/?f=10%287x%2B10y%29%20%3D%2010%2864%29%5C%5C70x%2B100y%3D640)
This will be equation 4.
Subtracting equation 3 from equation 4
![70x+100y - (70x+49y) = 640-385\\70x+100y-70y-49y = 255\\51y = 255\\\frac{51x}{51} = \frac{255}{51}\\x = 5\\Putting\ x=5\ in\ equation\ 1\\10(5)+7y = 55\\50+7y = 55\\7y = 55-50\\7y = 5\\\frac{7y}{7} =\frac{5}{7}](https://tex.z-dn.net/?f=70x%2B100y%20-%20%2870x%2B49y%29%20%3D%20640-385%5C%5C70x%2B100y-70y-49y%20%3D%20255%5C%5C51y%20%3D%20255%5C%5C%5Cfrac%7B51x%7D%7B51%7D%20%3D%20%5Cfrac%7B255%7D%7B51%7D%5C%5Cx%20%3D%205%5C%5CPutting%5C%20x%3D5%5C%20in%5C%20equation%5C%201%5C%5C10%285%29%2B7y%20%3D%2055%5C%5C50%2B7y%20%3D%2055%5C%5C7y%20%3D%2055-50%5C%5C7y%20%3D%205%5C%5C%5Cfrac%7B7y%7D%7B7%7D%20%3D%5Cfrac%7B5%7D%7B7%7D)
So,
Price of one citron = 5 units
Price of one fragrant = 5/7 units = 0.71 units
