1. ## I can´t solve this situation =S (algebra II)

Hello folks =)

This is a 'situation' that looks so simple to solve, but I don't realy know how to star it!

Here cames:

'A man bought product A, by US$96, and product B, by US$ 84. Know that: the total os products bought was 26, and the price of one product A is US\$ 2 more expensive than one product B. How many product A were bought?'

PS: I tried to make a system, using x = product A and y = product B, but than I get lost with the prices..... =(

2. Ahn

Can I do something like

$A = B + 2$ ?

3. Price of each A = a ; then price of each B = a-2
Number of A's = n ; then number of B's = 26 - n

an = 96
(a-2)(26-n) = 84

I'll leave you the pleasure of finishing it!
