Adler and Erika solved the same equation using the calculations below. Adlerâ€™s Work Erikaâ€™s Work StartFraction 13 over 8 EndFraction = k one-half. StartFraction 13 over 8 EndFraction minus one-half = k one-half minus one-half. StartFraction 9 over 8 EndFraction = k. StartFraction 13 over 8 EndFraction = k one-half. StartFraction 13 over 8 EndFraction (negative one-half) = k one-half (negative one-half). StartFraction 9 over 8 EndFraction = k. Which statement is true about their work? Neither student solved for k correctly because K = 2 and StartFraction 1 over 8 EndFraction. Only Adler solved for k correctly because the inverse of addition is subtraction. Only Erika solved for k correctly because the opposite of One-half is Negative one-half. Both Adler and Erika solved for k correctly because either the addition property of equality or the subtraction property of equality can be used to solve for k.
