in the pair of linear equations x+y=9&x-y=1 the values of x and y are__________​

2 thoughts on “in the pair of linear equations x+y=9&x-y=1 the values of x and y are__________​”

1. Answer:

   x=4 y=5

   Step-by-step explanation:

   x+y=9_1

   x-y=1 _2

   therefore, x=9-y _3

   Substituting value of x from eq 3 to eq 2 we get,

   9-y-y=1

   9-2y=1

   2y=9+1

   y=10/2

   y=5

   substituting value of y in eq 1 we get

   x+5=9

   thus, x=4

   Hope it helped you.

2. Answer-

   X= 5 , Y = 4.

   [tex] \sf{Given \: equations \: are – }[/tex]

   x + y = 9

   x – y = 1

   [tex] \sf{adding \: both \: equations}[/tex]

   [tex] \sf{x + y + x – y = 9 + 1}[/tex]

   [tex] \bf{therefore}[/tex]

   X= 5

   Putting x= 5 in given equation,

   y = 4
