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!

Answer:

x=22

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
to both sides gives
4x=88 .

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