Wayground 23: Solutions

Multiple Choice

Which of the following scenarios represents an equation with: No Solutions?

• Variables cancel out, resulting in a false statement (e.g., 3 = 12)

• A single value makes the equation true (e.g., 3 = 3)

• Variables cancel out, resulting in a true statement (e.g., 2x+1 = 2x+1)

• The equation has multiple answers
