Answer:

Solving the inequality
1<(a+7)/(-2) we get the value of a:
\mathbf{a<-9}

Explanation:

We need to solve the inequality:
1<(a+7)/(-2)

We need to solve the inequality, to find the value of a.

Solving the inequality:


1<(a+7)/(-2)

First step is Switching both sides (the inequality will be reversed)


(a+7)/(-2)>1

The next step is to multiply both sides by -2 and reverse the inequality


(a+7)/(-2)*-2<1*-2\\a+7<-2

Now, subtracting 7 on both sides


a+7-7<-2-7\\a<-9

So, solving the inequality
1<(a+7)/(-2) we get the value of a:
\mathbf{a<-9}
