Solving a two step equation with negative variable

The video tutorial explains how to solve an equation involving a negative variable. It begins with a problem statement and guides students through understanding the equation using inverse operations. The tutorial then demonstrates solving the equation step-by-step, focusing on handling negative signs. Finally, it verifies the solution to ensure accuracy.

What is the initial equation presented by the teacher?

• -X + 4 = 11

• X + 4 = 11

• X - 4 = 11

• -X - 4 = 11

What is the first step in solving the equation -X - 4 = 11?

• Add 4 to both sides

• Divide both sides by 4

• Multiply both sides by -1

• Subtract 4 from both sides

After adding 4 to both sides, what does the equation become?

• X = 7

• -X = 15

• X = 15

• -X = 7

How do you handle the negative sign in front of X in the equation -X = 15?

• Multiply both sides by 1

• Subtract 1 from both sides

• Add 1 to both sides

• Divide both sides by -1

What is the final value of X that satisfies the equation?

• 15

• 11

• -15

• -11
