Question

solution this
ax+by=a-b
bx-ay=a+b​

Answer 1

Answer:

ax+by=a−b .......... (1)

bx−ay=a+b .......... (2)

Multiply equation (1) with a and equation (2) with b ,

a

2

x+aby=a

2

−ab ..........(3)

b

2

x−aby=ab+b

=ab+b 2

=ab+b 2 ......... (4)

=ab+b 2 ......... (4)Adding (3) and (4), we get,

=ab+b 2 ......... (4)Adding (3) and (4), we get,(a

=ab+b 2 ......... (4)Adding (3) and (4), we get,(a 2

=ab+b 2 ......... (4)Adding (3) and (4), we get,(a 2 +b

=ab+b 2 ......... (4)Adding (3) and (4), we get,(a 2 +b 2

=ab+b 2 ......... (4)Adding (3) and (4), we get,(a 2 +b 2 )x=a

=ab+b 2 ......... (4)Adding (3) and (4), we get,(a 2 +b 2 )x=a 2

=ab+b 2 ......... (4)Adding (3) and (4), we get,(a 2 +b 2 )x=a 2 +b

=ab+b 2 ......... (4)Adding (3) and (4), we get,(a 2 +b 2 )x=a 2 +b 2

=ab+b 2 ......... (4)Adding (3) and (4), we get,(a 2 +b 2 )x=a 2 +b 2

=ab+b 2 ......... (4)Adding (3) and (4), we get,(a 2 +b 2 )x=a 2 +b 2 ⇒x=1

Now, from (1),

Now, from (1),ax+by=a−b

Now, from (1),ax+by=a−ba+by=a−b

Now, from (1),ax+by=a−ba+by=a−bby=−b

Now, from (1),ax+by=a−ba+by=a−bby=−by=−1
