The answer should have positive sign.
Explanation:
First you do is divide by -6 from both sides of an equation.
![(-6(2+a))/(-6)=(-48)/(-6)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/vqj7i5h2sy7pld4kul1esc06n0d440rnux.png)
Then, simplify and solve the problem.

![2+a=8](https://img.qammunity.org/2020/formulas/mathematics/middle-school/60cjb7qqk5sjertaejxab8uh8pm4ybk7fp.png)
Next, you switch sides.
![a+2=8](https://img.qammunity.org/2020/formulas/mathematics/middle-school/nsa2ddoqlbk1rtnyongo7qr2cc539u401n.png)
You subtract by 2 from both sides of an equation./
![a+2-2=8-2](https://img.qammunity.org/2020/formulas/mathematics/middle-school/kgl5nz3uaf2isgvwtl9xrukcpfq95x3y5y.png)
Finally, solve/simplify.
![8-2=6](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fal4d5y7ilsxi191dmq5wyvtin032ujnuc.png)
A=6 is the correct answer.
Hope this helps you!
Have a nice day! :)
