The problem is asking for a number, so let’s make that \(n\).Now let’s try to translate word-for-word, and remember that the “opposite” of a number just means to make it negative if it’s positive or positive if it’s negative.This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness.

Now let’s do some problems that use some of the translations above.
We’ll get to more difficult algebra word problems later. Solution: We always have to define a variable, and we can look at what they are asking.

Now that you can do these difficult algebra problems, you can trick your friends by doing some fancy word problems; these are a lot of fun.You know she makes an hour tutoring, and you already stated that the number of hours she tutors each week is x.So, the expression describing how much she makes each week tutoring is 30x.Some algebra problems on the GED Mathematical Reasoning test are straightforward: Solve a given equation for x.Once you know the basic rules for solving, these are pretty simple.The problem is asking for both the numbers, so we can make “\(n\)” the smaller number, and “\(18-n\)” the larger.\(\begin2n-3\,\,\,=\,\,18-n\\underline\3n\,-3\,\,=\,\,\,18\\underline\\,\,3n\,\,\,\,\,\,\,\,\,\,=\,\,\,21\\,\frac\,\,\,\,\,\,\,\,\,\,\,=\,\,\frac\\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,n=7\,\,\,\,\,\,\text\\,\,\,18-7=11\,\,\,\,\text\end\) Solution: We always have to define a variable, and we can look at what they are asking.So, you need to calculate: 3(340)=1,020 He uses 1,020 grams. So, the sum of the money received for bracelets, rings, and necklaces, will equal 245: 5x 20x 15x 45=245 So, you have one equation that you can solve for x, which is the number of bracelets sold: 5x 20x 15x 45=245 40x 45=245 40x=200 x=5 Remember that x equals the number of bracelets sold.But, you cannot simply subtract this from the total mass of the bag of flour, because the bag of flour is stated in kilograms. 2.27(1000)= 2270 grams Now, subtract the amount of grams of flour Oliver used from the total grams in the bag of flour: 2,270-1,020=1,250 5. So, the amount of money she makes from bracelets is given by the expression 5x. The problem asks you to find the number of bracelets, rings, and necklaces sold. Sarah is an educator and writer with a Master’s degree in education from Syracuse University who has helped students succeed on standardized tests since 2008.Now, you can use this information to solve for x using the first equation: x y=5 x 2=5 x=3 So, she tutors for 3 hours each week. C Your first step is to find out how many grams of flour Oliver uses. Fill out the table as you parse each piece of information in the problem.He uses 340 grams per batch of biscuits, and he makes three batches. So, the amount of money she makes from rings is given by the expression 10(2x). You know that in total she made 5 at the craft fair.
