Los Incas, la civilización e imperio más importante de América del Sur cuando llegaron los españoles a América, era una sociedad altamente democratizada e, incluso, elegían mediante sufragio o votación universal al emperador o Zapa Inca verdadero o falso ??

it was on the rise and doing very well and would continue to do well until the great depression from 1929-1939

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
