Incomplete question. Repost the complete problem.
Legnth are x and y
x+y=100
one is 16 more than other
x is 16 more than y
x=16+y
x=16+y therefor we can put 16+y for x
(16+y)+y=100
16+y+y=100
16+2y=100
minus 16 both sides
2y=84
divide by 2
y=42
sub back
x=16+y
x=16+42
x=58
the legnsh are
42 cm and 58cm
