Instead of simply providing a list of answers, we'll approach each problem type with detailed explanations.

Common Algebraic Concepts on Page 158 (Hypothetical Examples)

Since we don't have access to the specific questions on page 158, we will cover common algebraic concepts frequently found in such resources. These explanations will equip you to solve any problems you encounter on that page, regardless of their specific phrasing.

1. Solving Linear Equations

Linear equations are the backbone of elementary algebra. They involve finding the value of an unknown variable (usually represented by 'x' or 'y') that makes the equation true. A typical linear equation looks like this: ax + b = c, where 'a', 'b', and 'c' are constants.

Example: Solve for x: 3x + 7 = 16

Solution:

1. Subtract 7 from both sides: 3x = 9
2. Divide both sides by 3: x = 3

Therefore, the solution to the equation is x = 3. This process involves applying inverse operations (subtraction to undo addition, division to undo multiplication) to isolate the variable.

2. Simplifying Algebraic Expressions

Simplifying algebraic expressions involves combining like terms and using the order of operations (PEMDAS/BODMAS). Like terms are terms with the same variable raised to the same power.

Example: Simplify: 4x + 2y - x + 5y

Solution:

1. Combine like terms: (4x - x) + (2y + 5y)
2. Simplify: 3x + 7y

The simplified expression is 3x + 7y.

3. Working with Exponents

Exponents represent repeated multiplication. Understanding exponent rules is crucial for simplifying expressions with exponents. Key rules include:

• Product Rule: xᵃ * xᵇ = x⁽ᵃ⁺ᵇ⁾
• Quotient Rule: xᵃ / xᵇ = x⁽ᵃ⁻ᵇ⁾
• Power Rule: (xᵃ)ᵇ = x⁽ᵃ*ᵇ⁾

Example: Simplify: (x²)³ * x⁵

Solution:

1. Apply the power rule: (x²)³ = x⁶
2. Apply the product rule: x⁶ * x⁵ = x¹¹

The simplified expression is x¹¹.

4. Solving Systems of Linear Equations

Systems of linear equations involve finding the values of two or more variables that satisfy multiple equations simultaneously. Common methods for solving these systems include substitution and elimination.

Example: Solve the system:

x + y = 5 x - y = 1

Solution (using elimination):

1. Add the two equations: (x + y) + (x - y) = 5 + 1 This simplifies to 2x = 6
2. Solve for x: x = 3
3. Substitute x = 3 into either original equation to solve for y: 3 + y = 5, so y = 2

The solution to the system is x = 3 and y = 2.

5. Factoring Algebraic Expressions

Factoring involves expressing an algebraic expression as a product of simpler expressions. Common factoring techniques include factoring out the greatest common factor (GCF) and factoring quadratics.

Example: Factor: 3x² + 6x

Solution:

The GCF of 3x² and 6x is 3x. Therefore, the factored expression is 3x(x + 2).

6. Solving Quadratic Equations

Quadratic equations are equations of the form ax² + bx + c = 0, where 'a', 'b', and 'c' are constants. Methods for solving quadratic equations include factoring, the quadratic formula, and completing the square.

Example: Solve: x² - 5x + 6 = 0

Solution (using factoring):

1. Factor the quadratic: (x - 2)(x - 3) = 0
2. Set each factor equal to zero and solve: x - 2 = 0 or x - 3 = 0
3. Solve for x: x = 2 or x = 3

The solutions to the quadratic equation are x = 2 and x = 3.

Strategies for Solving Algebra Problems

• Understand the problem: Read the problem carefully and identify the unknowns and given information.
• Draw diagrams: Visual representations can help clarify complex problems.
• Break down complex problems: Divide large problems into smaller, more manageable steps.
• Check your work: Always verify your answers by substituting them back into the original equations or expressions.
• Practice regularly: Consistent practice is crucial for mastering algebraic concepts.
• Seek help when needed: Don't hesitate to ask for help from teachers, tutors, or classmates if you're struggling.
