Question 240645: One number is 4 more than twice the second number. Their total is 25. Find the numbers. I just need help on writing the problem, then I will be able to solve it.
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! Let x= the 2nd number. (I always like to let x = the quantity at the end of the sentence or phrase!)
Now, the first number is 4 more than twice the second number, where the second number is x.
Therefore, first number = 2x+4.
Now the equation is that the total (or sum!) of the numbers is 25.
x+2x+4=25
You said that you can solve it, so go for it!
I have a LOT of resources on my own website on the topic of WORD PROBLEMS. To find my website, do a "BING" or a "GOOGLE" search for my last name "Rapalje". Near the top of the search list, you should see "Rapalje Homepage." Click on this, and look near the top of my homepage for the link "Basic, Intermediate and College Algebra: One Step at a Time." Choose "Basic Algebra", and look in "Chapter 1" for "Sections 1.09 and 1.10, Word Problems." This is my own explanation especially written for students who have trouble understanding math. I wrote this to students, NOT mathematicians, and I think you will find it easier to understand than your own traditional textbooks!! In addition to this page, the entire website is supported by my "MATH IN LIVING COLOR" pages, where the hardest problems are solved IN COLOR.
If you like my website, please recommend it to family and friends who have trouble understanding math!! It's ALL FREE!!!
