Answer:  40 peaches

Step-by-step explanation:

Let x represent (1/2) the peaches

and y represent (1/2) the strawberries

          Peaches            Strawberries               Ratio

Alice:     x - 3                        y                           1:4

Bryan:     x                        y - 8                          1:3

We can create a system of equations:

Alice: 4(x - 3) = y      -->   4x - 12 = y

Bryan: 3(x) = y - 8  

Substitute y = 4x - 12 into the Bryan equation:

3x = (4x - 12) - 8

3x = 4x - 20

-x = -20

x = 20

Therefore, Alice and Bryan each had 20 peaches, which means Bryan bought a total of 40 peaches.
