<h2>
Larger number = 10</h2><h2>
Smaller number = 5</h2>
Step-by-step explanation:
Let larger number be x
Let smaller number be y
---> equation (i)

-----> equation (ii)
Equate equation (i) and (ii),

Move variable to L.H.S and change its sign:
Similarly, Move constant to R.H.S and change its sign


The difference sign (-) will be cancelled on both sides

Putting the value of y in equation (ii) in order to find the value of X ( larger number)

Plug the value of y

Calculate the product

Hence,
Smaller number = 5
Larger number = 10
Hope this helps..
