ok so remember
when 2 lines intersect the 2 opposite angles that face each other are equal measure
also, remember that a straight line=180
so
therefor BEA=CED and we want to find BEA, also
BED=180 so
BEC+CED=BED=180
aka
6x+7+5x-3=180
solve
6x+7+5x-3=180
combine
11x+4=180
subttract 4
11x=176
diivde 11
x=16
CED=AEB
CED=5x-3
subsitute
CED=5(16)-3
CED=80-3
CED=77
CED=77=AEB
answer is 77 degreees
