Question

find the value of Dx and D for the equation 2x+3y=4 ;
7x-5y=2​

Answer 1

Answer:

i think we can solve this equation this qay

7x-5y=2

1.) 7x-5y=2

    1/3x-1/2y=-1/6

 

2.)  x + y=2

    2x +3y=7

 

3.)  x  +y=6

     3x +3y=4

 

 

4.) x + 2y=5

     2x-y=-10

 

5.)  3x + y =1

      ______

              7

      x – 2y= 0
