Best Answer

Let x represent one of the numbers and (x - 2) the other number and set it up:

x + (x - 2) = 40

2x - 2 = 40

2x = 42

x = 21

The two numbers are 21 (x), and 19 (x - 2).

The difference of 2 numbers is 32 the sum is 158 what are the 2 numbers?

2 Numbers are a and b. We have( a>b) a+b=40(1) and a-b=10(2) a=10+b( from 2. Subtracts both side by b) => 10+b+b=40 (from 1. Substitute a with 10+b) => 10+2b =40 => 2b =30 => b =15 =>a=10+15=25 => a=25 b=15.

The sum of the numbers 1 to 39 = 39 x 40 ÷ 2 = 780 The sum of the numbers 1 to 60 = 60 x 61 ÷ 2 = 1830 Therefore the sum of the numbers 40 to 60 = 1830 - 780 = 1050

The two numbers are 10 and 2
