Simplifying Expressions (Part 1)

The video tutorial explains how to identify and combine like terms in a mathematical expression. It begins by identifying two pairs of like terms: 5X and 4X, and 3 and 7. The tutorial then demonstrates how to reorder the expression using the commutative property of addition to place like terms together. Finally, it shows how to add the like terms to simplify the expression to 9X + 10.

What are the two pairs of like terms identified in the expression?

How do you simplify a variable expression using like terms?

What is the result of adding the first pair of like terms, 5X and 4X?

What is the sum of the second pair of like terms, 3 and 7?

What does the expression simplify to after combining like terms?
