Answer»

ANSWER:

x = 27 y = 13

Step-by-step explanation:

LET the TWO numbers be x and y.

x + y = 40

x - y = 14

Using SUBSTITUTE method,

x = 40 - y

Applying temporary value if x in equation 2 i.e,

x - y = 14

40 - y - y = 14

=> 40 - 2y = 14

=> -2y = 14 - 40

=> y = 13

Now to find x,

x = 40 - 13

=> x = 27

Verification:-

27 +13

27- 13
