Answer: x=36°
Step-by-step explanation:
The four interior angles of a quadrilateral always equal 360°, so:
(x+16)+(4x-8)+(4x-8)+x=360
Combine like terms:
360=10x+0
360=10x
36=x
This system has exactly one solution, because the two equation are linearly independent (i.e. one is not a multiple of the other).
We can explicitly find the solutions: from the first equation we deduce

Plug this value for x in the second equation:

Multiply both sides by 6 to get

Plug this value for y in the expression for x:

Since both a,b are not zero, both solutions are well defined.
