2n+5n=35
7n=35
n=5
King Kong destroys 2n cities, or 10 cities. Godzilla destroys 5n cities, or 25 cities. Together they destroy 35 cities. (How many times can you destroy Tokyo?)..

Question is to find both..
K=cities destroyed by KK,
G=similar.
K:G = 2:5
Cross multiply:
5K=2G
G=(5/2)K
K+G=35= (1+5/2)K
(7/2)K=35
K=10
G=25
10+25=35
Not totally sure which are the 5 steps.
