Final answer:
The solution for the equation

Step-by-step explanation:
To solve the equation
for x, we can begin by multiplying both sides by (-0.5) to isolate x. This yields:

So, the value of x is 7.5. However, it's important to note that dividing a negative number by a negative number results in a positive value. In this case, (-0.5) divided by (-15) is (30), giving us the same positive solution:

In summary, the solution for the equation
. This can be achieved by either multiplying both sides by (-0.5) or recognizing the relationship between negative numbers, resulting in a positive value.
