Answer 2

Given :   ax+by =2

To find : One of the solutions

1] (1,2-b/a)

2] (2/b,/0)

3] (2-b/a,1)

4] (0,2/a)

Solution:

ax+by =2

=> by =  2 - ax

=> y = (2 - ax)/b

x = 1

=> y = (2 - a)/b

( 1, (2 - a)/b)

x = 0

=> y = 2/b

(0 , 2/b)

put y = 1

=>x = (2 - b)/a

(2-b)/a , 1

option 3rd is correct

put y = 0

=> x = 2/a

( 2/a , 0 )

(2-b)/a , 1

option 3rd is correct
