The second page focuses on more complex algebraic operations including expression evaluation, simplification, and solving equations for specific variables.

Highlight: The page demonstrates progressive complexity in algebraic thinking, moving from basic evaluation to complex variable manipulation

The content includes various types of mathematical operations:

• Expression evaluation with parentheses
• Simplification of algebraic expressions
• Solving equations for specific variables
• Working with proportions
• Solving inequalities with graphing

Example: Problem 19 shows the simplification of -5k - 5$k-3$ to -10k + 15

Definition: Proportion - an equation stating that two ratios are equal, typically in the form a/b = c/d

The page concludes with a bonus question involving multiple operations and variable manipulation, testing students' comprehensive understanding of algebraic concepts.

This page presents a variety of algebraic problems focusing on equation solving and real-world applications. The questions progress from simple equation solving to more complex word problems involving variables and real-life scenarios.

Example: Problem 1 demonstrates basic equation solving with -8 = x/2, resulting in x = -16

Highlight: The test includes multiple-choice questions that assess students' understanding of equation-solving strategies

Definition: Linear equations are mathematical statements that contain variables of degree one, such as ax + b = c

The page includes several word problems that connect mathematical concepts to real-world scenarios, such as calculating earnings from different hourly rates and analyzing cell phone plans.

Example: Kurt's earnings problem combines two different hourly rates $16f + 5b$ to create a total earnings expression

Vocabulary: Expression - a mathematical phrase that can contain numbers, variables, and operations
