Answer:

x=22

Step-by-step explanation:

Because \angle ABC=\angle ABD+\angle DBC=80^{\circ}, we have that (2x+4)+(2x-12)=80.

Combining like terms on the left side gives 4x-8=80.

Adding 8 to both sides gives 4x=88.

Dividing both sides of the equation by 4 gives \boxed{x=22}.

I haven’t done this in a while but I’ll try ….

2x - 12 + 2x + 4 = 80
4x - 8 = 80
+ 8 = + 8
4x = 88
Divide by 4
x = 22
Maybe… I hope it’s right!
