Algebra 1: Word Problems... Help?

(10-20-2010, 08:25 AM)Disease Wrote: I believe you made an error in your post, or there's a discrepancy in the problem itself. If the problem wants to you find four consecutive integers then it'd be:

x
x + 1
x + 2
x + 3


By jumping immediately from x to (x + 2) you're breaking consecution. Regardless, you need to write out the equation based on what they've given you. You know that it's the sum of four consecutive integers, represented by x, which each iteration adding one more than the last. Thus the problem can be represented as:

x + (x + 1) + (x + 2) + (x + 3) = 94

And of course you can simplify that equation.

4x + 6 = 94
4x = 88
x = 22

Then check your answer:

x + (x + 1) + (x + 2) + (x + 3)
22 + (22 + 1) + (22 + 2) + (22 + 3)
22 + 23 + 24 + 25 = 94


Ha, you aced the problem, and now I get it MUCH better! Thanks so much Disease!
