Solving Linear Equations Steps

The video tutorial explains how to solve an equation by isolating the variable. It begins with simplifying the equation through distribution and combining like terms. Next, it demonstrates how to isolate the variable by adding or subtracting terms. Finally, it shows how to solve for the variable by dividing both sides of the equation. The solution is verified by substituting the value back into the original equation to ensure it holds true.

What is the first step in solving an equation to find the value of x?

• Subtract a constant from both sides

• Add a constant to both sides
