Answer»

ANSWER:

income of a= 600 . income of b= 400 .

Step-by-step explanation:

let income of a and b 3X and 2x respectively.

also , their extend is 5y and 3y respectively.

from FIRST condition,

3x-5y =200........(1)

from second condition

2x-3y = 200........(2)

3(3x-5y) = 200

9x-15y =800.......(3)

5(2x-3y) = 200

10x-15y = 200.......(4)

subtract equation 3 and 4

9x-15y-10x+15y = 800-1000

-x = -200

x= 200

income of a = 3x

= 3×200

= 600

income of b = 2x

= 2 × 200

= 400
