 * Student Summaries:** In section 3-1 we learned how to determine if a number is a solution of an equation, and solve an equation. We determined how to find the answer to a question like such; 14x + 3 = 12x + 7. The answer is 2. - Austin Z.

We had to find if the supposed solutions were actually answers to the problem by plugging them in. Also we had to just solve a problem by doing the inverse of the equation. -Susie W.

**Students Summaries:** With the **addition property of equality**, whatever you add to either side they will be equal. If c=d c+f= f+d. With the **multiplication property of equality**, whatever you multiply to each side it will be equal. If c=d cf = df

you would divide both sides by 16 and get that f = 5 You would subtract 3 from both side and get that x = 9 -- Chantel D. and Bethany H.
 * Example 1:** 16f = 80
 * Example 2:** x+3=12

**Student Summaries:** This lesson explains two step equations which is an equation that requires to steps to solve. Example: 3x-7=14 Step 1 Add seven to both sides 3x=21 Step 2 Divide three from both sides x=7 --Ashley C and Keith W

Chapter 5 was all about proportions. To solve a proportion you may use cross-products which are equal. The word ratio, or used as a symbol ":" means to divide. A proportion is an equation stating that two ratios are equivalent. a is to b as c is to d a:b = c:d a/b = c/d - Jonathan Z.

**Student Summaries:** Lesson 3-6 is about reading ad graphing inequalities on a number you need to know what true and ,false, and open inequalities are. You also need to know what the inequality symbols are. - Matt B.

3-7: Solve Inequalities

 * Student Summaries:** In this lesson things that were learned in previous lessons were applied, such as solving equations. The only thing that changed was that there was an inequality sign instead of an equals sign. When multiplying or dividing you need to make sure you're careful because if you multiply or divide by a negative number the inequality sign needs to be flipped. - Sarah S.
