Examples, solutions, worksheets, videos, and lessons to help Grade 7 students learn how to use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.
B. Solve word problems leading to inequalities of the form px
, where p
, and r
are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem. For example: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100. Write an inequality for the number of sales you need to make, and describe the solutions

Suggested Learning Targets
Solving Inequalities by Adding or Subtracting
- I can solve simple inequalities.
- I can solve two step linear inequalities of the form px+ q > r and px+q < r, where p, q, and r are specific
- I can solve word problems (two-step linear inequality
problems) with rational coefficients (ex, px +q = r).
- I can graph the solution sets of inequalities.
- I can interpret the solution sets of the inequality.
When you add or subtract the same number from each side of an inequality, the inequality remains true.
1. Solve -21 ≥ d - 8. Check your solution.
2. Solve y + 5 > 11. Check your solution.
3. Kayla took $12 to the bowling alley. Shoe rental costs $3.75. What is the most he could spend on games and snacks?

How to Translate Word Problems Into Multistep Inequalities?
In this lesson, we'll go over some word problems, which, in order to find their solution, require us to translate them into (multi-step) inequalities -- inequalities which take more than one step to solve.
Writing An Inequality From A Word Problem
The elevator of a local school has a maximum weight capacity of 2,000 pounds. If there are already 3 people on the elevator that have a combined weight of 460 pounds, write an inequality expressing the possible weights that may be added to the elevator. Use "w" to represent the weight.
When John bought his new computer, he purchased an online computer help service. The help service has a yearly fee of $25.50 and a $10.50 charge for each help session a person uses. If John can only spend $170 for the computer help this year, what is the maximum number of help sessions he can use this year?
