![x=-8](https://img.qammunity.org/2022/formulas/mathematics/high-school/fz2mhy546dc7igdq3umfh5y8wsax1i93av.png)
Explanation:
Let's say that the number is x. Hedi adds 5 to the number, then multiplies its sum by -2. The result is 6. Writing this out as an equation:
![-2(x+5)=6](https://img.qammunity.org/2022/formulas/mathematics/high-school/9n5ve6prdtu9dj8vchke6z192fb5g2vcyw.png)
So now we solve for x. First, we divide both sides by -2, giving us:
![x+5 = -3](https://img.qammunity.org/2022/formulas/mathematics/high-school/s0noa0zq81xlhin4vawr88krvzhyh95x4j.png)
Then, to finish the problem, we subtract 5 from both sides:
![x=-8](https://img.qammunity.org/2022/formulas/mathematics/high-school/fz2mhy546dc7igdq3umfh5y8wsax1i93av.png)
Thus, the number Hedi started with was -8
Hope this helps!
