Question

the sum of two numbers is 2. if their difference is 20, find the two numbers

Answer 1

Heya !!



Let two numbers are X and Y.


Sum = 2


X + Y = 2 -------(1)

And ,


Difference = 20



X - Y = 20 ---------(2)


From (1) we get,


X + Y = 2


X = ( 2 - Y ) ----(3)

Putting the value of x in (2)


X - Y = 20


2 - Y - Y = 20

-2y = 18




y = -9


Putting the value of y in (3)



X = 2 - Y



X = 2-(-9) = 11



Hence,


Two numbers are -9 and 11.

Answer 2

Your Answer :-

Let the numbers be x , y

then ,

x + y = 2

x - y = 20

$\boxed{A.T.Q.}$

We have ,

x + y = 2

x = 2 - y ----------- Equation 1 .

Putting Value of x in Another Equation ,

x - y = 20

2 - y - y = 20

2 - 2y = 20

-2y = 18

y = - 9 .

then ,

x = 2 - y

x = 2 - (-9)

x = 11.
