Algebraic Expressions

Manipulating Variables and Solving Equations

Algebra helps you generalize and solve problems using variables. You'll encounter expressions, equations, and inequalities.

Key Concepts

  • Simplifying algebraic expressions
  • Solving linear equations and inequalities
  • Substitution and factoring

Why It Matters

Algebra is used in budgeting, predicting trends, and even figuring out how long it will take to reach a savings goal.

Problem-Solving Approach

  • Isolate the variable using inverse operations.
  • Check your solutions by plugging them back into the original equation.
  • Watch for extraneous solutions in inequalities.

GRE Focus

On the GRE, you may need to interpret word problems and write equations that model real situations.

Examples

  • Solve for \( x \): \( 2x - 5 = 9 \).

  • If \( y = 3x + 2 \) and \( x = 4 \), what is \( y \)?

In a Nutshell

Algebra is about representing and solving problems with variables.
