hakirat can u help me please

Answer 17

ok it will be solved as follows:

multiply first equation by 3 and second equation by 4 to get

27x -12y = 6000 -------(A)
28x - 12y = 8000 --------(B)

Now subtract (B) from (A) to get

-x = - 2000

so x = 2000

Now put x = 2000 in the given first equation to get value of y

9(2000) - 4y = 2000
-4y = 2000 - 18000
-4y = -16000
y = -16000/ -4

y = 4000
