Answer
$-7$
Work Step by Step
We start with the given expression: $6(-9)-(-8)-(-7)(4)+11$
Order of operations states that first, we perform operations inside grouping symbols, such as parentheses, brackets, and fraction bars. Then, we simplify powers. Then, we multiply and divide from left to right. Then, we add and subtract from left to right. We follow order of operations to simplify:
First, we multiply and divide from left to right: $-54-(-8)-(-28)+11$
Next, we add from left to right: $-54+8+28+11=-46+28+11=-18+11=-7$
