Q. 7

# If the sum of two numbers is 89 and their difference is 15, let’s find the two numbers.

Let two numbers be x and y,

Then according to the given criteria

x+y=89

Hence the y=89-x is another number

Given the difference of both the numbers is 15

Hence

x-(89-x)=15

x-89+x=15

2x=89+15

2x=104

And the other number is y=89-x=89-52=37

Hence the two numbers are 52 and 37
