Homework Help: algebra

Posted by ken on Saturday, April 21, 2007 at 11:34pm.

I have been working this one for awhile and have become more confused. Please assist.
Problem:
Find two consecutive odd integers such that 5 times the first interger is 12 more than 3 times the second.

The key thing is to realize that odd numbers, just like the even numbers, are 2 apart
So if you let the first odd number be x, then the second odd number is x+2

Now all you do is translate the English into math.

"...such that 5 times the first interger is 12 more than 3 times the second."

5x > 3(x+2) by 12

so we add 12 to the smaller side to make it into an equation.

5x = 3(x+2) + 12

easy to solve
