Answer:

(1, -6)

Step-by-step explanation:

the layout of your question is kind of confusing, but i'm guessing this is the system of equations

x = -y - 5

-3x + 7y = -45

plug in x to the second equation

-3(-y - 5) + 7y = -45

distribute

3y + 15 + 7y = -45

combine like terms

10y = - 60

divide by 10

y = -6

plug y into first equation

x = -(-6) - 5

x = 6 - 5

x = 1

Did the Native Americans The pilgrims encountered lived in tipis and traveled on horseback?
USPshnik [31]
<span>Answer: The fields Indians lived in tipis. Indians in New England would have solidified to death in tipis. Furthermore, obviously stallions are not indigenous to the New World, so Indians didn't have them until the point that the White Man brought them. In any case, the Pilgrims were not the main Europeans in the New World, by any extend of the creative ability, so it's conceivable a few Indians had stallions by at that point. When we think about the word 'Indian' we promptly get a photo of a fields Indian, the Sioux or the Lakota. I think this is generally a direct result of our extraordinary legacy of western motion pictures about cowhands and Indians. The Indians on the East Coast were altogether different from that photo of buckskins, interlaces, plumes in the hair, and so on. The entire story of the Pilgrims is covered in myth and false history. For a certain something, they weren't generally Pilgrims. They weren't even truly Puritans! They were a chip assemble from the standard Puritan people group, calling themselves 'Precisionists'. They didn't come here to build up a group of religious opportunity, however one that they could keep running by their own particular religion. They didn't put stock in the partition of chapel and state (as our establishing fathers did), they trusted the congregation WAS the state. In any case, at that point a considerable measure of the American history we learn in primary school and secondary school is this way, more a teaching than an instruction. When you examine American history in school you need to unlearn all you've been shown up until this point.</span>
