Answer:
We get the value of a:

Explanation:
We have to solve the inequality

So, solving the inequality and finding value of a
First step is to switch both sides and for doing so, the inequality will be reversed

Multiply both sides by -2, as we are multiplying by a negative number, the inequality will be reversed


Now, subtracting both sides by 7, to find value of a

We get the value of a:
