Describe the development of the trade between mesopotamia and egypt.

Ancient Egypt was a very popular place for trading in their time. The Egyptians traded gold, papyrus, linen, grain, and sometimes they would sell artifacts stolen from a pharaohs tomb. They would normally trade these items for cedar wood, ebony, ivory, lapis lazuli, incense, myrrh, iron, and copper.

simplify brackets

8 - 2a - 7 = a + 40

simplify 8 - 2a - 7 to -2a + 1

-2a + 1 = a + 40

add 2a to both sides

1 = a + 40 + 2a

simplify a + 40 + 2a to 3a + 40

1 = 3a + 40

subtract 40 from both sides

1 - 40 = 3a

simplify 1 - 40 o -39

-39 = 3a

divide both sides by 3

-39/3 = a

simplify 39/3 to 13

-13 = a

switch sides

a = -13
