Explanation of Coefficients:

In mathematics, a coefficient is a numerical or constant factor in a term of an algebraic expression. It is the number that is being multiplied by a variable. For example, in the expression 5x, the coefficient is 5, and in the expression -3y, the coefficient is -3.

Study Guide for Coefficients:

1. Definition: A coefficient is the numerical factor in a term of an algebraic expression.
2. Identifying Coefficients: Look for the number being multiplied by a variable in an algebraic expression.
3. Examples:
   • In the expression 4x, the coefficient is 4.
   • In the expression -2y, the coefficient is -2.
   • In the expression 3xy, the coefficient is 3.
4. Operations with Coefficients: Coefficients can be added, subtracted, multiplied, and divided just like regular numbers.
5. Solving Equations: Coefficients are crucial for solving equations and isolating variables.
6. Practice Problems: Practice simplifying algebraic expressions by identifying and working with coefficients.
