Answer 1

Step-by-step explanation:

let 1st no. is x

and 2nd no. is y

A.T.Q

x+y=42

x=42-y

x-y=16

42-y-y=16

-2y=16-42

-2y=-26

y=14

x=42-14

x=28....

Answer 2

Answer:

x = 29 and y = 13

Step-by-step explanation:

Let the numbers be x and y.

Given that :

x + y = 42. ...(1)

x - y = 16. ...(2)

Subtracting equation (2) from equation (1),

x + y = 42

- x - y = 16

- + -

2y = 26

2y = 26

y = 26/2

y = 13

From equation (1),

x + y = 42

x + 13 = 42

x = 42 - 13

x = 29
