3x + 6y = 10 is the equation to determine of an apple x and the price of an orange y
Solution:
Let the price of each apple = $ x
Let the price of each orange = $ y
Martha bought 3 apples and 6 oranges
She had $10 in her wallet which was enough money for the purchase
Thus the equation is:
Total amount = 3 apples(price of each apple) + 6 oranges(price of each orange)
Thus we get,
[tex]10 = 3x + 6y\\\\3x + 6y = 10[/tex]
Thus the equation is found
