Solving Linear Equations Concepts

The video tutorial demonstrates solving linear equations in one variable through two examples. It begins with simplifying both sides of the equation, eliminating parentheses, and combining constants. The first example involves distributing -7 and isolating the variable by subtracting and dividing. The solution is x = 10. The second example uses similar steps, distributing 8, combining constants, and isolating the variable by subtracting and dividing, resulting in x = 10. The tutorial emphasizes simplifying equations and isolating variables to find solutions.

What is the first step in solving linear equations with multiple steps?

• Multiplying both sides by a constant

• Adding constants

• Simplifying both sides of the equation

• Isolating the variable
