Algebraic Expressions and Equations

What Are Variables?

Variables are symbols (like \( x \) or \( y \)) that represent unknown values. Algebraic expressions combine variables and numbers using operations.

Simplifying and Solving

  • Simplify: Combine like terms and use properties of numbers.
  • Solve: Find the value of the variable that makes the equation true.

Equation Example

You might see something like \( 2x + 3 = 11 \). To solve, subtract 3 from both sides and then divide by 2.

Why Algebra Matters

Algebra is like a puzzle that helps you solve for unknowns—perfect for everything from science experiments to budgeting!

Key Formula

\[2x + 3 = 11\]

Examples

  • Simplify \( 4x + 2x - 3 \).

  • Solve \( x/2 = 6 \) for \( x \).
