To solve basic algebra word problems, identify the variable or unknown quantity, translate the problem into an equation, simplify and solve the equation, and answer the question with the appropriate units.
A more thorough response to your request
Algebra word problems can seem intimidating at first, but with a few simple steps, they can become much more manageable. The first step is to identify the variable or unknown quantity in the problem. This is the piece of information that we are trying to solve for. For example, if the problem states that John has three apples and gives us information about how he shares them with his friends, the variable might be the number of apples that John has left at the end of the scenario.
Once we have identified the variable, the next step is to translate the problem into an equation. This means using mathematical symbols to represent the information given in the problem. For example, if we are trying to solve for the number of apples that John has left, we might use the equation:
3 – x = y
where x is the number of apples that John gives away and y is the number of apples he has left.
After we have created the equation, we can simplify it by combining like terms and isolating the variable on one side of the equation. For example, to solve for x in the equation above, we would add x to both sides and get:
3 – y = x
Finally, we can answer the question with the appropriate units. For example, if the problem asks us how many apples John has left, we would write our answer as:
John has 3 – y apples left.
As the famous mathematician Albert Einstein said, “Pure mathematics is, in its way, the poetry of logical ideas.” Algebra word problems require us to use logical ideas to solve real-world scenarios.
Interesting facts on algebra:
- Algebra is a branch of mathematics that originated in the Middle East over 1,000 years ago.
- The word “algebra” comes from the Arabic word “al-jabr,” which means “the reunion of broken parts.”
- Algebra uses symbols and letters to represent unknown values. This allows us to solve problems that might otherwise require large amounts of arithmetic.
- Many famous mathematicians, including Isaac Newton and Galileo Galilei, used algebra to make major scientific discoveries.
- The quadratic formula, which is used to solve quadratic equations, is over 4,000 years old and was first discovered in ancient Babylon.
Here is a table summarizing the steps to solve basic algebra word problems:

In the “Algebraic Word Problems” video, Professor Dave illustrates how algebraic equations can be used to solve word problems. He presents real-life scenarios and demonstrates how to assign variables and construct equations based on the given information. He then shows how to solve the equations by algebraic manipulation to obtain the answers to the problems.
