Answer:
x=6
Step-by-step explanation:
all the details are in the attached picture. The suggested solution is not the shortest way.
Note, step 1 is: to find the domain; step 2 is: to solve the equation wihout domain; step 3: to determine 'x' with domain. The answer is marked with green colour.
Substitutethe point (x1, y1) i.e. (4, 32), and m = 4 (since the lines are parallel they have the same slope) into the equation
y -y1 = m(x - x1)
e.g. y - 32 = 4 (x - 4)
