Answer 2

Answer:

solve by substitution method.

a+b= 13

a= 13-b

put this value in ab=12

then, a + (13-b) = 12

a + 13-b = 12

a - b = -1

solve a+b=13 and a-b = 12 by elemination method...

then, 2a = 25

a = 12.5

and put a= 12.5 in a+b =13

then, b = 13-12.5

b= 0.5

so, value of a = 12.5 and b = 0.5 that is ur answer.

hope it will help u.......
