Many students find solving algebra word problems difficult. The best way to approach word problems is to “divide and conquer”. Break the problem down into smaller bits and solve each bit at a time. An online math tutor can help you to learn this type of technique.
First, we need to translate the word problem into equation(s) with variables. Then, we need to solve the equation(s) to find the solution(s) to the word problems.
We need to recognize some common types of algebra word problems:
Age Problems usually compare the ages of people.
They may involve a single person, comparing his/her age in the past, present or future.
They may also compare the ages involving more than one person.
Average Problems involve the computations for arithmetic mean or weighted average of different quantities.
Another common type of average problems is the average speed computation.
Coin Problems deal with items with denominated values.
Similar word problems are Stamp Problems and Ticket Problems.
Consecutive Integer Problems deal with consecutive numbers.
The number sequences may be Even or Odd, or some other simple number sequences.
Digit Problems involve the relationship and manipulation of digits in numbers.
Distance Problems involve the distance an object travels at a rate over a period of time.
We can have objects that Travel at Different Rates, objects that Travel in Different Directions or we may need to find the distance Given the Total Time
Fraction Problems involve fractions or parts of a whole.
Geometry Word Problems deal with geometric figures and angles described in words.
This include geometry word problems Involving Perimeters, Involving Areas and Involving Angles
Integer Problems involve numerical representations of word problems.
The integer word problems may Involve 2 Unknowns or may Involve More Than 2 Unknowns
Interest Problems involve calculations of simple interest.
deal with the lever principle described in word problems.
Lever problem may involve 2 Objects or More than 2 Objects
Mixture Problems involve items or quantities of different values that are mixed together. This involve Adding to a Solution, Removing from a Solution, Replacing a Solution,or Mixing Items of Different Values
Motion Word Problems are word problems that uses the distance, rate and time formula.
Number Sequence Problems use number sequences in the construction of word problems. You may be asked to find the Value of a Particular Term or the Pattern of a Sequence
Proportion Problems involve proportional and inversely proportional relationships of various quantities.
Ratio Problems require you to relate quantities of different items in certain known ratios, or work out the ratios given certain quantities. This could be Two-Term Ratios or Three-Term Ratios
Variation Word Problems may consist of Direct Variation Problems, Inverse Variation Problems or Joint Variation Problems
Work Problems involve different people doing work together at different rates.
This may be for Two Persons, More Than Two Persons or Pipes Filling up a Tank

Angela sold eight more new cars this year than Carmen. If together they sold a total of 88 cars, how many cars did each of them sell?
Example: One number is 4 times as large as another. Their sum is 45. Find the numbers.
Example: Devon is going to make 3 shelves for her father. She has a piece of lumber 12 feet long. She wants the top shelf to be half a foot shorter than the middle, and the bottom shelf to be half a foot shorter than twice the length of the top shelf. How long will each shelf be if she uses the entire 12 feet of wood?
