Solving One-Step Equations

In this video, Mr. J explains how to solve one-step multiplication equations involving negative numbers. The process involves isolating the variable by using the inverse operation, which is division in this case. Two examples are provided: solving for x in the equation negative 6x = negative 36, and solving for e in 77 = negative 7e. The video emphasizes the importance of performing the same operation on both sides of the equation to maintain balance. Each solution is verified by substituting the variable back into the original equation.

What is the first step in solving one-step multiplication equations with negatives?

• Add a constant to both sides

• Use the inverse operation

• Subtract a constant from both sides

• Multiply both sides by zero
