Where on earth are cacao farms generally found?

The cocoa farms are generally found in the area called as the cocoa-belt. This cocoa belt is a narrow band of the land, which exists up to 20 degrees to the South and the North. Ghana and Indonesia are among the top cocoa growing countries. Warm and hot temperatures with high humidity and high rainfall are needed for the growth of the cocoa trees.

Hence, the answer is 'Cocoa trees grow in the cocoa belt which exists up to 20 degrees to the South and the North'.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
