Description (paste on Stuvia)
Clear and simplified college mathematics notes covering linear equations and inequalities.
Includes definitions, worked examples, and practice questions. Suitable for beginners and
revision.
Content
1. Linear Equations
A linear equation is an equation with one or more variables raised to the power of 1.
Example:
2x + 3 = 11
Solution:
2x = 8
x=4
2. Solving Linear Equations
Combine like terms
Move variables to one side
Solve for the unknown
3. Linear Inequalities
An inequality shows a relationship that is not equal.
Symbols used: >, <, ≥, ≤
Example:
3x − 2 > 7
3x > 9
x>3
4. Practice Questions
1. Solve: 4x + 6 = 18
