Q. Solve for aa.\newline12a−16a=−812a - 16a = -8\newlinea=a = ____
  1. Combine like terms: Combine like terms on the left side of the equation.\newline12a−16a=(12−16)a12a - 16a = (12 - 16)a\newline=−4a= -4a
  2. Set equation equal: Set the equation equal to −8-8.−4a=−8-4a = -8
  3. Divide both sides: Divide both sides by −4-4 to solve for aa.−4a−4=−8−4\frac{-4a}{-4} = \frac{-8}{-4}a=2a = 2
