Describe the geographic significance of the gupta empire, and explain how this contributed to the movement of people and ideas

I wrote The Huns were near the Gupta Empire. The Huns constantly tried to invade the Gupta Empire but failed. This resulted in the Guptans wanting to move. The Gupta Empire also invented the number 0 and the idea that the Earth spins on its axis.

I hope this is what your looking for : )

Please rate & thank : )

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
