Answer 1

Answer:

22, 20

Step-by-step explanation:

Let the two numbers be x and y

x+y=42____1

y=42-x

x-y=2____2

Putting the value of y in eq. 2

x-42+x=2

2x-42=2

2x=2+42

2x=44

x=22

Putting the value of y in eq. 1

x+y=42

22+y=42

y=42-22

y=20

Answer 2

Answer:

Given That ;

Sum of two numbers is 42,

Difference of two numbers = 2

Let ;

The numbers ,

First number = x

Second number = y

• x + y = 42 ---- ( 1 )
• x - y = 2 -------( 2 )

Elimination Method :

Adding Both the Equations :

x + y = 42

x - y = 2

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

2x = 44

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

Hence ;

2x = 44

x = 44 / 2

x = 22

Substitute x = 22 in Equation ( 1 ) :

x + y = 42

22 + y = 42

y = 42 - 22

y = 20

CHECKING :
Substitute x & y values in Equation ( 2 ) :

x - y = 2

22 - 20
