**Find the number of calories in a banana and a peach. 1) A banana contains 65 more calories than a peach. 2) Eight peaches have 20 fewer calories than 3 bananas.**

**Answer:**

Let number of calories in a banana = b

and number of calories in a peach = p

Then 1) b = 65 + p

2) 8p = 3b - 20

This gives p = 35 and b = 100
