Identify Operation: Which operation should be used to isolate a?In 11−12a=−97, we should first subtract 11 from both sides to isolate the term containing a.Subtract 11 from both sides: 11−12a−11=−97−11
Subtract and Isolate: Find the value of a after subtraction.−12a=−97−11−12a=−108Now, divide both sides by −12 to solve for a.
Calculate Value: Calculate the value of a.−12−12a=−12−108a=9
