Simplify the expression $-2(n-9)+4$ .

STEP 1

Assumptions1. The expression is $-(n-9)+4$ . We need to simplify this expression

STEP 2

First, we need to distribute the $-2$ to both terms inside the parentheses. This means we multiply $-2$ by $n$ and $-2$ by $-9$ .
$-2(n-9) = -2 \cdot n -2 \cdot -9$

STEP 3

Now, calculate the multiplication.
$-2 \cdot n -2 \cdot -9 = -2n +18$

STEP 4

Now, we add the $4$ to the result of the distribution.
$-2n +18 +4$

STEP 5

Finally, we simplify by adding the constants together.
$-2n +18 +4 = -2n +22$ The simplified form of the expression $-2(n-9)+4$ is $-2n +22$ .
