A friend told Sandy that absolute value makes everything positive so Sandy wrote the equation |x-6|=5 as x+6=5. Do you agree with the statement, or with what Sandy did to the equation? Explain your answer.
Sandy is incorrect. Absolute value marks serve the same purpose as parenthesis. So to solve the equation correctly, you would find the answer to x-6. Absolute value is the distance from zero, so the answer is 5. For example, if the answer was -5 then the answer would still be 5 because it is 5 units away from zero.
