B = age Brooklyn Bridge
B - 54 = age Golden Gate Bridge
B - 54 = 23/50 * B
50B - 50*54 = 23B
27B = 50*54
27B = 2700
B = 100
1983 - 100 = 1883 for Brooklyn Bridge
1883 + 54 = 1937 Golden Gate Bridge

---------------------
1983 Equations:
G = B+54.
G = (23/50)B
------
1983 Equation:
B+54 = (23/50)B
---
(27/50)B = -54
B = -100
------------------
1983 Solutions:
G = -100 + 54
G = -46
-----------------
Brooklyn Bridge built in 1983-100 = 1883
Golden Gate built in 1983-46 = 1937
