Normally you will see these expressions in reverse order with descending powers of the variable.
-4y^4 + y^3 - y^2 + 11y + 9
So you start with the high order terms and end with a constant.
1) add, equal
2) multiply, equal
3) subtract, equal

Answer:
∠ ABC = ∠ DBE = 65°
∠ ABD = ∠ CBE = 115°
Step-by-step explanation:
See the diagram attached to this question.
Now, ∠ ABC and ∠ DBE are two vertically opposite angles.
So, 3x + 38 = 5x + 20
⇒ 2x = 18
⇒ x = 9
So, ∠ ABC = ∠ DBE = 3(9) + 38 = 65° (Answer)
Again, ∠ ABC and ∠ ABD are supplementary angles.
Then, ∠ ABC + ∠ ABD = 180°
⇒ ∠ ABD = 180° - 65° = 115°
And ∠ ABD = ∠ CBE {Vertically opposite angles}
So, ∠ ABD = ∠ CBE = 115° (Answer)
