Question

Cedric and Insha solved the same equation using the calculations below. Cedric's Work Insha's Work z minus 4.5 = negative 1.5. Z minus 4.5 + 4.5 = negative 1.5 + 4.5. Z = 3. z minus 4.5 = negative 1.5. Z minus 4.5 + (negative 4.5) = negative 1.5 + (negative 4.5). Z = negative 6. Which statement is true about their work? Cedric is correct because he used the inverse of subtraction and added 4.5. Cedric is incorrect because he should have subtracted 4.5 from both sides instead of adding. Insha is correct because she added the opposite if 4.5, which is Negative 4.5, to both sides. Insha is incorrect because she did not add Negative 1.5 + (negative 4.5) correctly.
