Callie solved this one-variable equation. When she was done, she tried to verify her answer, but found that it was wrong. Can yo

u find her mistake? 1 2 (4k + 8) = 10 1. 2k + 16 = 10 2. 2k = −6 3. k = −3 What was Callie’s mistake? Callie should have added 10 to both sides in step 2. In step 1, when Callie distributed the One-half to the 8, she multiplied incorrectly. Callie divided by 2 instead of multiplying by 2 in step 3. Callie should have added 16 to both sides in step 2.
