Hi,
<span>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?
</span>
<span></span>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.
