Question

solve for n.
11.7 = \frac{n}{2}- - 8.1
n =

Explanation:

Step1: Simplify the double - negative

The equation $11.7=\frac{n}{2}-(- 8.1)$ simplifies to $11.7=\frac{n}{2}+8.1$ since subtracting a negative is the same as adding a positive.

Step2: Isolate the term with $n$

Subtract 8.1 from both sides of the equation: $11.7 - 8.1=\frac{n}{2}+8.1 - 8.1$. This gives $3.6=\frac{n}{2}$.

Step3: Solve for $n$

Multiply both sides of the equation by 2 to get $n$ alone. So, $n = 3.6\times2$.

Answer:

$7.2$
