Answer 2

Answer:

Step-by-step explanation:

let monthly income of A = x

---------------------------of B = y

let expenditure of A = 7y

-------------------------B = 5x

let income of A = 5y

-----------------B = 4x

according to statement

5x - 7y = 3000 ...... (1)

4x - 5y = 3000 ...... (2)

5x - 7y = 3000 *4

4x - 5y = 3000 *5

20x - 28y = 12000

20x - 25y = 15000

- + -

~~~~~~~~~~~~~~~

0 - 3y = - 3000

y = 1000
