Solving One Step Equations with Integers

The video tutorial explains how to solve one-step equations using integers. It covers the process of isolating the variable by performing opposite operations on both sides of the equation. Two examples are provided: solving x + 7 = -24 and x - 9 = -21. The tutorial emphasizes understanding integer operations and provides analogies to aid comprehension.

What is the main goal when solving a one-step equation?

• To isolate the variable on one side of the equation

• To divide both sides of the equation

• To multiply both sides of the equation

• To add numbers to both sides of the equation
