Answer 2

Answer:

Therefore the no.'s are 31/2 and -17/2

Step-by-step explanation:

Let the first no. is = X

and the second no. is = y

Given data =

(x+y) = 7 is (eq1)

(x-y) = -24 is (eq2)

from (eq1) and (eq2)

x + y = 7

-x + y = 24

------------------

+2y = 31

y = 31/2

y = 31/2 in eq1

x+31/2 = 7

x = 7 - (31/2)

x = 14 - 31/ 2

x = (-17/2)
