Solving Linear Equations and Operations

The video tutorial explains how to solve a linear equation in one variable by isolating the variable, distributing terms, and simplifying the equation. It demonstrates the process of solving the equation -4(3x - 2) = 42, including distributing the negative 4, isolating the variable term, and solving for x. The solution is simplified to x = -17/6, and the tutorial verifies the solution by substituting it back into the original equation to ensure it holds true. The video emphasizes understanding the steps involved in solving and checking linear equations.

What is the first step in solving a linear equation?

• Add a constant to both sides

• Isolate the variable on one side

• Divide by the coefficient of the variable
