The video tutorial discusses justifying solutions for equations using properties. It begins by revisiting the order of operations and introduces four equality properties: addition, subtraction, multiplication, and division. These properties ensure that operations are performed equally on both sides of an equation. The tutorial provides two examples, demonstrating how to justify each step in solving equations using these properties. The video concludes with a practice problem for students to apply what they've learned.
