Question

use the elimination method to solve the system
-x+2y=10
-3x+6y=11
Options
A-infinite solutions
B-(-5,2)
C-(5,-2)
D- no solutions
Please show work

Answer 1

just solve equation one for x
x=2y-10
put this in the second equation at the place of x
-3(2y-10)+6y=11
so
-6y+10+6y=11

can you find that 0y=11
what do you think it is possible?

Answer 2

wat do u mean

Answer 3

i mean y=11/0 ?? what does it mean ?

Answer 4

that does not work that's not even one of the answers

Answer 5

you have calculator ?

Answer 6

yes i have the calculator in my hand

Answer 7

ok just find this and let me know what it says !
11/0

Answer 8

ther is no way i could put that in a calculator if 11/0 is 0 duh

Answer 9

always remember that division by zero is undefined and is not possible!

Answer 10

yea but i dont get where u got the 11 from its so confusing

Answer 11

and u cant put the first problem into the second one that is not possible

Answer 12

look at your second equation there is 11 on the right .
and sorry there is a typo in my response!
just solve equation one for x
x=2y-10
put this in the second equation at the place of x
-3(2y-10)+6y=11
so
-6y+10+6y=11
so 0y=1
this equation mans means
\[\Large 0=1\]
which is not possible so system has no solution.

Answer 13

hes right the answer is D

Answer 14

hhhhhhhhhhheeeeeeeeellllllllllpppppppppp me still lost

Answer 15

hhhhhhhhhhhhhhhhheeeeeeeeeeeeeeeeeeeeeeeeeelllllllllllllllllllllllllllpppppppppppppppp

Answer 16

ok tell me what you are unable to understand.
just tell me is it possible that?
\[\Large 0=1\]
