Question

What are those two numbers whose sum is 58 and difference is 28?
is 56
​

Answer 1

Step-by-step explanation:

Let the two numbers be x and y,then according to the question,

x+y=58 and x−y=28

Adding the above two equations

x+y+x−y=58+28

2x=86

x=43

Putting the value of x in any of the equations

43+y=58

y=58=43=15

Therefore the numbers are 44 and 15

Answer 2

Answer:

Steplet the numbers be x and y

x+y=58

x-y=28

add these both expressions

x+y=58

x-y=28

=2x=86

y becomes zero because any number with + and - is zero so i did not mention it

then x=86 divided by 2=43

so x=43

x+y=58

43+y=58

y=58-43=15

therefore these are the two numbers
