are these angles supplementary or complementary?

if angles supplementary they add up to 180°:
m<ABE%2BEBF=180=> 2n%2B7%2B+4n+-13=180
6n-6=180...both sides divide by 6
6n%2F6-6%2F6=180%2F6
n-1=30
n=30%2B1
n=31
then m<ABE=+2%2A31%2B7=62%2B7=69
ABE=+69°

but, if angles complementary they add up to 90°:
m<ABE%2BEBF=90=> 2n%2B7%2B+4n+-13=90
6n-6=90...both sides divide by 6
6n%2F6-6%2F6=90%2F6
n-1=15
n=15%2B1
n=16
then m<ABE=+2%2A16%2B7=32%2B7=39
ABE=+39°
