6=7x
Now we divide both sides by 7 to isolate x:
x=6/7

French Indochina included all of the following EXCEPT

ExtremeBDS [4]

1. B) Burma. France controlled all of the territories listed in Southeast Asia except for Burma. This is because Burma belonged to the UK. Both the UK and French expanded into Southeast for the purpose of acquiring regions during imperialism to obtain raw materials. The French were expelled from the Indochina region following the Vietnam war.

2. B) Japan. Following WWI, the Japanese began to expand a great deal of military and political influence over East Asia and the Pacific. Japan was an industrious island nation, in need of resources for its factories. It also saw itself as the dominant race and nation of East Asia due to its victory over Russia in the early 20th century and its desire for legitimacy in the face of Europe. For these reasons, Japan expanded tremendously around Asia and the Pacific, taking the Dutch East Indies during WWII.
