a bag of peaches has 3 more than 2 times the number of bananas in a bag of bananas. if there are 17 peaches in a bag, how many bananas are in the bag of bananas?

this can be turned into an equation to be solved more easily. so the amount of bananas can be x. there are 17 peaches. So the equation would be:
(17 - 3) ÷ 2 = x
you begin with what's inside the parenthesis
17 - 3 = 14.
14 ÷2 = 7
x = 7
there are 7 bananas in the bag of bananas
