Solve a one step equation using addition with decimals

The video tutorial addresses a common student mistake in solving equations. It begins by introducing the problem of isolating a variable in the equation -5.1 + z = 9.2. The instructor explains the importance of understanding the operation affecting the variable and corrects the misconception that z is being added. Instead, z is subtracted from -5.1. The tutorial demonstrates rewriting the equation and using the addition property of equality to solve it, resulting in z = 14.3. The video concludes by confirming the solution and reinforcing the correct approach.
