Answer 2

HEYA...✋✋✋✋✋✋

HERE IS YOUR ANSWER......

Let the two numbers be x and y

the sum of x and y is 75
x+y=75--------------------------(1)

the difference of two numbers is 15
x-y=15----------------------------(2)

subtracting 1 from 2
x+y=75
x-y=15
------------

2x=90
x=45

when x =45 then substituting in eq( 1)
x+y==75
45+y=75
y=75-45
y=30

the two numbers are 45 and 30
