Here I hope this helps the answers is 0,7
Given: ∠AEB = 11x - 12, ∠CED = 4x + 1, Line EC bisects ∠BED
To find: ∠AEC
Since Line EC bisects ∠BED, ∠BEC = ∠CED
That is: ∠BEC = 4x + 1
Therefore ∠BEC + ∠CED = 4x + 1 + 4x + 1 = 8x + 2
Now, ∠AEB = 11x - 12
Therefore: ∠AEB + ∠BEC = ∠AEC
That is, 11x - 12 + 4x + 1 = ∠AEC
∠AEC = 15x - 11
Therefore ∠AEC = 15x - 11
Hopeit helps :)
