Ok
First we need to find x

9 < 4x - 7

Since the equation is not set up properly we need to switch it from right to left.

7 - 4x > 9

Now we solve

7 - 4x > 9

First we add 7 on both sides

7- will be 7+

-7+7 =0

9 + 7 = 16

Next we divided 4 on both sides

4/4=0 ( I know it should be 1 but that’s how it goes)

16/4= 4

So x=4

Equation

X > 4

this symbol > on a time line always must be open.

Since the symbol is facing left on the time line it must face the opposite side which is right.

So the answer is D
