Equations and Inequalities Word Problems Worksheets
Inequalities are mathematically comparisons of values as where equations are all about displaying equality. Equations are math statements that shows two equal expressions. Inequalities state that one side of the math statement is larger or smaller than the other. These worksheets and lessons teach students how to write equations and inequalities that are based on word problems. This will empower your students to solve much more complex problem types that will require critical thinking skills that they should be ready for at the high school level. The goal is for them to be able to read these word problems and represent them with mathematical statements of their own.

Math Skill Quizzes
This can be a challenging task for many students.
- Quiz 1 - Two road crews are paving a straight section of road. The first crew has completed paving 12 miles and is completing 2 additional miles per day. The second crew has finished 8 miles and is completing 3 miles per day. How long will it take for both teams to cover the same number of miles?
- Quiz 2 - Vijay was renting a skateboard for his competition training. Skateboard A is $12 per month and requires a down payment of $100. Skateboard B is $15 per month rent and requires a down payment of $80. How many months would Vijay need to rent the skateboard in order for the total cost to be same?
- Quiz 3 - Marlin and Watson are playing video games. Marlin has 40 points and is earning 5 points every turn. Watson has 50 points and is earning 3 points every turn. In a certain number of turns, the score will be tied. How many points will they each have?
How to Write a System of Equations
When you are solving real-world algebraic equations, you can get easily confused. Considering that such problems are complex to solve and are known as the system of equations. Let us consider an example to learn its concept quickly. David spent $131 one pair of shoes, since one pair of sneakers had a price of $15, while the slippers had a cost of $28. In total, he bought 7 pairs of shoes. How many pairs of each shoe did he buy of each type?
In this section, we are only learning how to write the system of equations and not solve them. In this problem, we have to write two equations, given that there are two variables. The two variables are the two pairs of shoes, i.e., the sneakers and the slippers. Let us consider the two variables like x and y. Now, in total, David bought 7 pairs of shoes comprising of the two variables. So, the first equation becomes:
[1] => x + y = 7
The first equation depicts the number of shoes bought by David. The second equation will illustrate the total money he spent. He spent a total of $131 comprising of $15 worth of x’s and $28 worth of y’s. So, the equation becomes:
[2] => 15x + 28y = 7
Now, you have two equations that you need to simultaneously solve to find out how many pairs did David bought for each type of shoes.
