Hello folks =)
This is a 'situation' that looks so simple to solve, but I don't realy know how to star it!
'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?'
Can somebody, please, help me???
PS: I tried to make a system, using x = product A and y = product B, but than I get lost with the prices..... =(
