Question

The sum lf two numbers is 10. The difference between the two numbers is 4: what is the smaller numerical?

Answer 1

Explanation:

x, y are the 2 numbers.

x + y = 10

y - x = 4

that gives us

y = x + 4

and we use that in the first equation :

x + x + 4 = 10

2x = 6

x = 3

y = x + 4 = 3 + 4 = 7

so, yes, the smaller number is 3.

The two numbers are 3 and 7, and 3 is the smaller one
