Question

i need help badly!! Solve this system of equations. Write the answer as an ordered pair.
-5x - 2y = -2
x - 7y = -7

Answer 1

what did u come up with...and show ur work

Answer 2

for some reason i thought it was asking for the equation...all i have is..... -5(7y-7)-2y=-2

Answer 3

multiply the bottom eq by 5 to cancel out the x when u add the equations

Answer 4

x-35y+35-2y=-2

Answer 5

could the answer be (1,-7)

Answer 6

no
doesn't fit in

Answer 7

AHHHHHH!!!!!!!!

Answer 8

wait maybe i can help

Answer 9

ok

Answer 10

Answer 11

are you finding people who might know?

Answer 12

yeah

Answer 13

ppl are nice here they might help

Answer 14

@goformit100

Answer 15

iight cool, its not like any of my teachers

Answer 16

my teachers never wanted to help

Answer 17

-5(7y-7)-2y=-2

-35y + 35 - 2y = -2

-37y = -37

y = ?

Answer 18

-1

Answer 19

think again

Answer 20

-37y = -37

divide 37 both sides
-y = -1

multiply -1 both sides
y = 1

Answer 21

oh, duh

Answer 22

substitute this value in any on of the given equations and solve x

Answer 23

thanks @ganeshie8

Answer 24

yeah, thank you @ganeshie8

Answer 25

np :) maybe substituting in second equation is slightly easier :

x - 7y = -7

x -7(1) = -7

x - 7 = 7

x = 0

Answer 26

so the solution of given system is ` (0, 1) `

Answer 27

Notice that we always write the x coordinate first.

Answer 28

ok now i get it too

Answer 29

yeah i knew the (x,y). some how i had (1,-7)

Answer 30

what about this one? Solve this system of equations. Write your answer as an ordered pair.
y + 6 = x
2x + 2y = 0

Answer 31

hey @ganeshie8 , how did you get -37
