Question

write any four solution of the equations pie x -y=9​


please help as soon as possible

Answer 1

Answer:

0 & - 9

1 & - 8

2 & - 7

3 & - 6

Step-by-step explanation:

Subtitute x = 0,

=> x - y = 9

=> 0 - y = 9

=> y = - 9

Solution = (0, - 9)

Subtitute x = 1,

=> x- y = 9

=> 1 - y = 9

=> y = 1 - 9 = - 8

Solution = (1, -8)

Subtitute x = 2,

=> x - y = 9

=> 2 - y = 9

=> y = 2 - 9 = - 7

Solution = (2, -7)

Subtitute x = 3,

=> x - y = 9

=> 3 - y = 9

=> y = 3 - 9 = - 6

Solution = (3, -6)

Answer 2

Question:

write any four solution of the equations pie x -y=9

Solution:

Given:

Given equation is x - y = 9

Now,

1 st solution:

substitute y = 0

=> x - y = 9

=> x - 0 = 9

=> x = 9

•°• (x , y) = ( 9, 0)

2 nd solution:

substitute y = 1

=> x - y = 9

=> x - 1 = 9

=> x = 10

•°• ( x, y ) = (10, 1)

3 rd Solution:

substitute y = 2

=> x - y = 9

=> x - 2 = 9

=> x = 11

•°• ( x,y ) = (11 , 2)

4 th solution:

substitute y= 3

=> x - y = 9

=> x - 3 = 9

=> x =12

•°• ( x,y ) = (12,3)
