The sum of two consecutive even integers is 154. Find the integers.
You can use the equation: (x) + (x+2) = 154. Now solve for x. Do you know how to solve this equation?
Yes, no, or are you still solving it?
well i dont really know how to solve it
what does consecutive mean?
numbers lik 2,4,6,8
Well, that is even consecutive. Though you get what consecutive mean.
yea...so how do you solve the equation?
I'm not the best at explaining on how I obtain that equation, but I'm sure Loser66 can.
@Jewell64 what if they are not even, how can I know whether they are consecutive or not,? like 1, 2, 3.....
No, no, @GoldPhenoix I am asking her the things I don't know
To solve the equation, pretend the parenthesis isn't there. The reason why I put parenthesis is to split them up into integer. (x) = Smallest integer (x+2) = Largest integer Add 2 because it says even. ^_^ So your equation would look like: x + x + 2 = 154.
well. consecutive even are all the even numbers lik 2,4,6,8,10 etc. Consecutive odd are all the odd numbers @Loser66
Yep. Now back to the equation: x + x + 2 = 154 The first step is to combine like term. So x + x = ?
thank you
Also, if you don't understand how to do it, then just say so. :)
isnt x the same as 1?
Not necessarily. x by itself is 1x. x is a variable. It can be any number. Hmm... You can say x is 1... for now. 1 + 1 =?
2 @GoldPhenoix
so would it be 2x+2=154? @GoldPhenoix
Yes! Perfect. You want x by itself in one side of the equation. So you want to get rid of 2. To get rid of 2, you want to do inverse operation. So 154 - 2 =?
so subtract 2 from both sides and u end up with 2x=152. then divide by 2 right?
@GoldPhenoix
Yep. What do you get?
x=76
@GoldPhenoix
Perfect. Now like I said before: x = Smallest number x + 2 = Largest number. Since 76 is the smallest number, what's the largest number?
78? @GoldPhenoix
Good job! 76, and 78 are your numbers! To check your work just see: Are those consecutive numbers? Do these two add up to 154? You don't have to reply, just check to see if it's right. ^_^
they do!! thank you so much! @GoldPhenoix
No problem!~
