Question

To solve x+y=3;3x-2y-4=0 find D

Answer 1

Explanation:

i didn't understand question

Answer 2

Answer:

D= (2, 1)

Explanation:

x+y=3 --1 equation

3x-2y = 4 ---2 equation

multiply equation 1 by 2 ...... therefore..2x+2y = 6

now by eliminating method

+2y and -2y get cancelled

and 3x+ 2x = 5x and also 6+4 = 10

hence 5x = 10

x = 10/5 ......x = 2

substitute x=2 in equation 1

2+y=3 ...y=3-2.....y=1

so ....the answer is x=2. y=1

so D= (2,1)...
