Answer:
The solution of the inequality is
.
Explanation:
The given inequality is
![-3x<7.5](https://img.qammunity.org/2019/formulas/mathematics/middle-school/1t6owolhwnshh94yxwfkzk2s13vkisryuq.png)
If an inequality divided by a negative number,then the sign of inequality change. Divide both sides by -3.
![(-3x)/(-3) >(7.5)/(-3)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/79mj4ue2x1isjxth1lir60jmkn1zbd2quf.png)
![x >-2.5](https://img.qammunity.org/2019/formulas/mathematics/middle-school/ka9raqasdye1974s4zmiy15su89eptzcvm.png)
Therefore the solution of the given inequality is all real numbers greater than -2.5.
In interval notation it can be defined as
