Question

The sum of two numbers is 16. Their difference is 1. What is the product of the two numbers?

Answer 1

Answer:

Step-by-step explanation:

Answer 2

x+y = 16 and y-x = 1

y = 1 +x

x + (1+x) =16

2x = 15

x = 15/2

so y = 1 + 15/2

=17/2

now product, x×y = (15/2)× (17/2)

= 255/4

=63.75
