-->6x+7×4=4 -->x=-4
#4 a reflection across the x-axis is the only correct answer , the other ones aren’t correct .
After solving
we get value of x: 
Step-by-step explanation:
We need to solve the equation
and find value of x:
Solving:

Using the rule: if 
Since our base is equal i.e 4 so,

So, After solving
