MArishka [77]
<h3>Answer:</h3>

(5/7, 12/7) <- I think you meant to type that. Its the first one

<h3>Step-by-step explanation:</h3>

Step 1: Substitute y=x+1 in for y in 5x + 2y = 7

5x + 2(x+1) = 7

Step 2: Solve it

5x + 2x + 2 = 7

       7x + 2 = 7

             - 2  - 2

              7x = 5

              ---    ---

               7     7

                x = 5/7

Step 3; Plug x into y=x+1

y = 5/7 + 1

y = 12/7

Number of ways of selection 5 flowers = 12C5 = 12!/{5!*(12-5)!} = 12!/{5!*7!} = 792

Therefore, there are 792 ways in which 5 flowers can be selected from the available 12 flowers.
