Hi,
Miranda bought some apples and oranges at the store for fruit salad. Owen bought three times as many apples and twice as many oranges. Miranda has 5 fruits in her bag, but Owen has 12 fruits in his bag. How many apples did Miranda purchase?
Derive two simultaneous equations a + o = 5 and 3a + 2o = 12 make a = 5 - o substitute in 2nd equation and you find o = 3, Miranda buys 2 apples.
