y = something x plus or minus a number
going through each line it isn't a linear pattern ( they don't all have the same difference when subtracted or added together)
so now you play around with quadratic equations ( square roots, powers, etc.)
and you will see that y = x^2 -5

Answer:
x = 13
Step-by-step explanation:
A linear pair of angles sum to 180° , then
2x + 9 + 10x + 15 = 180 , that is
12x + 24 = 180 ( subtract 24 from both sides )
12x = 156 ( divide both sides by 12 )
x = 13
