Question

1o. find the value of D. for the equation 4x+3y=
19 and 4x - 3y=-11​

Answer 1

Step-by-step explanation:

4x + 3y = 19 . . . . . (1)

4x - 3y = -11 . . . . . .(2)

(1) * 1 + (2) * 1

4x + 3y = 19

4x - 3y = -11. (strike out 3y )

8x = 8

or , x = 1

from (1)

4x + 3y = 19

or , 4 + 3y = 19. (putting the value of x)

or , 3y = 19 - 4

or , 3y = 15

or , y = 5

1. x = 1
2. y = 5
