Answer:
see below
Step-by-step explanation:
l -4 +2x l -3 > 9
Add 3 to each side
l -4 +2x l -3+3 > 9+3
l -4 +2x l > 12
We Separate into two inequalities, remembering to flip the negative inequality
-4+2x>12 or -4+2x<-12
Add 4 to each side
-4+4+2x>12+4 or -4+4+2x<-12 +4
2x> 16 or 2x< -8
Divide each side by 2
2x/2 > 16/2 or 2x/2 < -8/2
x > 8 or x < -4
To graph we have open circles at 8 going to the right and at -4 going to the left

Step-by-step explanation:
<u>Sequential Operations </u>
Mathematical operations can be done in sequence or in batches if they are of the same type. For example, we can add many terms in one single operation, but we cannot add and multiply in one go, because there are priorities when dealing with products and sums. Same happens with powers.
In our problem we are required to perform a sequence of operations like follows
Add s to t:
Add the result to r
Raise what you have to the 7th power
This is the final result
