Question

solve the following pair of linear eqation by the cross multiplicaton method :
8x+5y=9
3x+2y=4
​

Answer 1

Answer:

Step-by-step explanation:

given

   8x + 5y = 9 ------------->1

   3x + 2y = 4 -------------->2

 multiply eq 2 with 5,

   15x + 10y = 20---------------> 3

multiply eq 1 with 2

   16x + 10y = 18----------------> 4

    eq 3 -  eq 4

 

   15x + 10y -( 16x - 10y)= 20 - 18

   -x = 2

 x = -2

  -6 + 2y = 4

2y = 10

y = 5
