Q. Simplify the expression: \newline9+6+7r9 + 6 + 7r
  1. Identify Like Terms: Identify like terms in the expression 9+6+7r9 + 6 + 7r. In this expression, 99 and 66 are like terms because they are both constants without variables. The term 7r7r is not like a term with 99 or 66 because it contains a variable.
  2. Combine Like Terms: Combine the like terms (constants) in the expression.\newline9+6+7r9 + 6 + 7r\newline= (9+6)+7r(9 + 6) + 7r\newline= 15+7r15 + 7r\newlineWe added the constants 99 and 66 to get 1515.
