Answer 2

Answer:

Hi

here's your answer

Given-

=》x+y = 5 ____ eq. 1

=》x-y = 8 ____ eq. 2

On adding equations 1 and 2

=》x+y+x-y = 13

=》2x = 13

=》 x = 6.5

Now, substituting x in any of the given equations ( I am substituting in eq. 1 )

=》6.5+ y = 5

=》 y = -1.5

OR

x = 65/10 = 13/2

y = -15/10 = -3/2

hope it helps
