Question

the sum of two numbers is 43.the differance is 13 find the numbers​

Answer 1

Answer:

let the numbers be x and y.

their sum is 43, so x + y =43 .

their difference is 13, so x - y = 13.

on adding above equations, we get

x +y +x -y = 43+13

2x = 56

x = 56/2

x = 28.

then,

x+y =43

28+y =43

y=43-28

y= 15.

Hence, the numbers are 28 and 15.

Answer 2

Answer:

The numbers are 28 and 15

Step-by-step explanation:

Let the numbers be a and b

=a+b=43

Their difference = 13

=a-b=13

To find the numbers we need to add the sum and the difference

=a+b+a-b=43+13

=a+b+a-b=56

=2a=56

=a=56/2=28/1

=a=28

To find b we need to use the main equation

Which is a+b=43

a+b=43

=28+b=43

=b=43-28

=b=15

Therefore b=15

Thus,

The numbers are 28 and 15
