x = 20
Step-by-step explanation:
The indicated angles are vertical and therefore congruent, hence
6x - 10 = 3x + 50 ( subtract 3x from both sides )
3x - 10 = 50 ( add 10 to both sides )
3x = 60 ( divide both sides by 3 )
x = 20

We can set up the following equation:

where
is the total number of shapes on Abigail's paper.
Let's first multiply both sides by
:

Next, let's multiply both sides by
:

Finally, let's divide both sides by
:
