Answer:
Step-by-step explanation:
12x - 3 = 180 - (7x - 26) supplementary angles
19x = 209
    x = 11
m∠DEC = 12(11) - 3 = 129°
m∠BCE = 7(11) - 26 = 51° 
M∠ADE = 129 - 72 = 57°  exterior angle rule
m∠EDB = 180 - 57 = 123° supplementary angles
m∠DBC = 57° corresponding angle to ADE

90 because there are 5 time as many candies with nuts as candies without nuts and there is 18 so it will be 18×5=90
        
             
        
        
        
The x,y = -6, -5. Hope this helped, and have a great day! :D
