Can someone please help me solve for x for me?????It’s for my test and please show the work so that way I know how to do it now:( I need some serious help here!!!!

Answer:
x = 6°
Step-by-step explanation:
∠7 and ∠5 are equal because the two intersecting lines are parallel.
The equation is:
78° = 12x + 6°
Subtract 6 from both sides
72° = 12x
Divide by 12 on both sides
6° = x
x = 6°
