as he turned to go, he spat speculatively.
he knew that at fifty below spittle crackled on the snow, but this spittle had crackled in the air.
as for lunch, he pressed his hand against the protruding bundle under his jacket.
he plunged in among the big spruce trees.
a foot of snow had fallen since the last sled had passed over, and he was glad he was without a sled . .

x=4, y=4

step-by-step explanation:

y=2x-4;

x+2y=12

we can use substitution since the first equation is solved for y

where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

distribute the 2

x+4x-8 = 12

combine like terms

5x-8=12

add 8 to each side

5x-8+8=12+8

5x=20

divide by 5

5x/5 = 20/5

x =4

we still need to solve for y

y = 2x-4

we know x =4

y = 2(4) -4

y = 8-4

y=4

hello everyone my name is nevaeh, i know everyone needs in some way, shape, or form and i am willing to provide. i set up a google classroom where people can ask me questions and get on work. no question is a stupid question so do not be afraid to ask. i usually only focus on core subjects but if you ask i will with other specialized subjects. i can do essays all the way to power points : )
