Understanding Algebraic Expressions

The video tutorial explains how to solve simple algebraic equations by combining like terms. It provides three examples: solving 2x - x = 7, 3x - x = 6, and 4x - 2x = 10. The instructor demonstrates how to simplify the equations by subtracting like terms and then dividing to find the value of x. Each example is broken down step-by-step to ensure understanding.
