Question

Sum 140 difference 80 fund the numbers

Answer 1

Answer:

Y =30 and X=110

Step-by-step explanation:

Let the two numbers be x and y

$x + y = 140$

Let

$x > y$

Then

$x - y = 80$

(i)

$x = 80 + y$

When we substitute for x with (i)

Then

$80 + y + y = 140$

$2y + 80 = 140$

$2y = 140 - 80$

$2y = 60$

$y = \frac{60}{2}$

$y = 30$

Then x

$x = 80 + 30$

$x = 110$

Hope you got the answer

Answer 2

Given :  Sum of two numbers = 140

Difference = 80

To Find :  Numbers

Solution:

Let say numbers are  a  and b

a  + b = 140   Eq1

a - b = 80      Eq2

Adding both equations

a + b + a - b = 140 + 80

=> 2a = 220

=> a = 110

Substitute in Eq1

=> 110 + b = 140

=>  b = 140 - 110

=> b = 30

Hence two numbers are 110 and 30
