Question

A + b = 9
a - b = 6
what is a/b?

Answer 1

5

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

5

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
