To simplify the expression \( 11 - 9(-2x - 3) \), follow these steps:
-
Distribute the \(-9\) to both terms inside the parentheses: \[ -9(-2x) - 9(-3) = 18x + 27 \]
-
Now substitute this back into the expression: \[ 11 + 18x + 27 \]
-
Combine the constant terms \(11\) and \(27\): \[ 11 + 27 = 38 \]
-
Therefore, the simplified expression is: \[ 18x + 38 \]
So, the final answer is: \[ 18x + 38 \]
