3(-y+2)+2y=12
-3y+6+2y=12
-y +6 = 12
-y = 6
y= -6
x = 6 + 2 = 8
(8, -6)

Answer:
Angle <em>ADE</em> is an obtuse angle.
Step-by-step explanation:
An obtuse angle is an angle that "opens" greater than 90 degrees. The question asks which angle is an obtuse angle, so basically you follow the order of letters and see which one is greater than 90 degrees (btw, 90 degrees, also known as a right angle, looks like the corner of a square, and anything greater than that is an obtuse angle).
Y=15/7x+2
