john buys apples for 8 rands each and tim buys oranges for 12 rands each. In total they buy 10 items for R104. how many oranges did tim buy

Answer 1

If x is the number of apples, y is the number of oranges

You have 2 equations:
x + y = 10
8x + 12y = 104 or
2x + 3y = 26 after reducing the equation

now double the first, then subtract from the second to get y
then go back into the first to get x

Answer 2

Thank you very much.
