One number is 3 less than twice another and their sum is 39 find the numbers?
let x be one number and y be the other The first thing given is that x is 3 less than twice y so x=2y-3 and x+y=39 so x=39-y and substitute this into the first equation a 39-y=2y-3 42=3y y=14 and x=39-14 or 25 Answer x=25 and y=14 Now lets check it 25 is 3 less than 2x14 (YES) 14+25=39 (YES) Done

Determine if a number is divisible by 3?
Check the sum of the digits, if the sum divisible by 3 then the number is divisible by 3. Example 910: the sum of digits= 9 + 1 + 0 = 10, but 10 is not divisible by 3, so the number 910 is not divisible by 3. Example 2154: the sum of digits = 2 + 1 + 5 + 4 = 12, this sum is divisible by 3, so the number 2154 is divisible by 3. if the sum is long you can check the sum of the sum and apply the same rule. Example 52498731: the sum of digits = 5 + 2 + 4 + 9 + 8 + 7 + 3 + 1 = 39, the sum of the digits for 39 = 3 + 9 = 12, so the original number, i.e. 52498731 is divisible by 3.
