Q. Simplify the expression:\newline−9a−3a+−6a+7a-9a - 3a + -6a + 7a
  1. Combine like terms: Combine like terms by adding and subtracting the coefficients of aa.−9a−3a+−6a+7a-9a - 3a + -6a + 7a=(−9−3−6+7)a= (-9 - 3 - 6 + 7)a
  2. Perform arithmetic operations: Perform the arithmetic operations within the parentheses.\newline(−9−3−6+7)(-9 - 3 - 6 + 7)\newline= −9−3−6+7-9 - 3 - 6 + 7\newline= −12−6+7-12 - 6 + 7\newline= −18+7-18 + 7\newline= −11-11
  3. Multiply simplified coefficient: Multiply the simplified coefficient by aa.−11a-11a
