Example Problems and Their Solutions
To illustrate the variety of practice problems, here are a few examples along with their solutions:
Example 1: Solving a Linear Equation
Problem: Solve for \( x \): \( 2x + 3 = 11 \).
Solution:
1. Subtract 3 from both sides: \( 2x = 8 \).
2. Divide by 2: \( x = 4 \).
Example 2: Solving a System of Equations
Problem: Solve the system:
- \( 2x + y = 10 \)
- \( x - y = 1 \)
Solution:
1. From the second equation: \( y = x - 1 \).
2. Substitute into the first: \( 2x + (x - 1) = 10 \).
3. Simplifying gives \( 3x - 1 = 10 \) or \( 3x = 11 \) thus \( x = \frac{11}{3} \).
4. Substitute back to find \( y = \frac{11}{3} - 1 = \frac{8}{3} \).
Example 3: Quadratic Equation
Problem: Solve \( x^2 - 5x + 6 = 0 \).
Solution:
1. Factor the equation: \( (x - 2)(x - 3) = 0 \).
2. Set each factor to zero: \( x - 2 = 0 \) or \( x - 3 = 0 \).
3. Solutions are \( x = 2 \) and \( x = 3 \).
