Answer 1

Answer:

5

Step-by-step explanation:

hello :

a + b = 9

...(*)

a - b = 6...(**)

add (*) and (**) : 2a =15.....(1)

subsct (**) and (*) : 2b=3  ....(2)

now divid (1) , (2) :  2a/2b = 15/3

means : a/b = 15/3 =5

Answer 2

Answer:

5

Step-by-step explanation:

a = 9 - b

9 - b - b = 6

9 - 2b = 6

9 - 6 = 2b

3 = 2b

b = 3/2

a = 9 - b

a = 9 - (3/2)

a = 15/2

a/b = (15/2) / (3/2)

a/b = 5
