Understanding Algebraic Expressions
Algebra is the language of mathematics, and it starts with understanding variables, constants, and coefficients. Let's dive into these fundamental elements!
Topics Covered:
What is a Variable?
Variables are symbols that represent unknown values. In algebra, common variables are x, y, and z.
Constants and Coefficients
Constants are fixed values like 1, 2, or 3. Coefficients are numbers multiplied by variables, such as in 3x or -5y.
Example Problems:
Solve for x in the equation: 2x + 3 = 7
Solution: Subtract 3 from both sides, then divide by 2.
