I think the answer is C 2/3
I think that you multiply 2 with 4 to get 8 and then multiply 8 with 7 to get that number then add 2.75... to get the total.
Hope it helped..
X=44°
you write 2x-6=82, subtract 6 on both sides so ur left with 2x=88, you divide both sides by 2 and you get 44
the answer is 
subtract 6x on both sides → 
divide both sides by -2y →
