Amelia wants to solve the equation shown on the Equation Mat at right. After she simplified each expression as much as possible, she was confused by the tiles that were left on the mat. What was Amelia's original equation? Remove any zero pairs that you find on each side of the Equation Mat. What happens? What is the solution to this equation? That is, what value of makes this equation true? Explain your reasoning. Equation Mat, with an equal sign in the center, with tiles as follows: Left side, 2 positive, x's, 1 negative, x, 1 positive unit, and 1 negative unit. Right side, 1 positive, x, 1 negative, x, 3 positive units, and 3 negative units. 6-52.
