I need help with this math problem. It says
If the lesser of two consecutive even integers is tripled, the result is 20 more than twice the greater integer. Find the two integers
Two consecutive integers means that they are right beside one another, think 32 and 33 for example. So if the first integer is X, then the second one is X+1. Now we read the problem, if the lesser of the two integers (X) is tripled (3X) the result is 20 more than twice the greater integer [20 + 2 (X+1)].
Thanks for taking the time to help out and explain
Two consecutive EVEN integers
(2n) and (2n+2)
2n < 2n+2
"If the lesser number is tripled, the result is 20 more than twice the greater number"
3(2n) = 2(2n+2)+20
6n = 4n+24
2n = 24
n = 12
2n = 24
2n+2 = 26
