x=7
Answer:

Step-by-step explanation:
The equation of the given line:

This equation is in the form
. Therefore, 1/3 is the slope.
To find a perpendicular line, take the opposite reciprocal of the slope (-1/old slope). Therefore, the slope of the perpendicular line is -3.
The equation of the perpendicular line:
