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
I hope this helped, have a nice day
