If five apples and three oranges cost as much as six pears and if three pears cost the same as two apples and five oranges, how many oranges will be of the same value as three pears and an apple?

[sandyRoe]

an apple is worth 7 oranges...
And then I get lost, sorry

Correct SandyRoe
So if you add an apple to each side of the second statement you get;
3p + 1a = 3a + 5o
Replace the 2 apples on the right with 3x7 oranges
3p + 1a = 21o + 5o = 26o
3 pears + 1 apple = 26 oranges
