Question

Use elimination to solve the system of equations. Enter your answer as an ordered pair
2x-5y=-5
-2x+8y=-58

Answer 1

is the ans (-55,-21)

Answer 2

\[2x-5y=-5,~~~ -2x+8y=-58 \implies 3y=-63 \implies y=-21 \implies x=-50 \]\[\implies (x,y)=(-50,-21)\]

Answer 3

can you do one more

Answer 4

matiricked is correct; bad mental math by me.

Answer 5

2x+6y=-8
5x-3y=88

Answer 6

thankyou

Answer 7

mention not

Answer 8

thanks matricked can you do the other problem i listed

Answer 9

is the ans(14,-6)

Answer 10

one more? and thnks agn

Answer 11

you are a boss man

2x-y=2
3x-2y=11

Answer 12

\[\left(\begin{matrix}2x+6y=-8 \\ 5x-3y=88\end{matrix}\right)\implies 12x=168 \implies x=14 \implies y=-6 \implies (x,y)=(14,-6)\]

Answer 13

thanks animal

Answer 14

can you one more
2x-y=2
3x-2y=11

Answer 15

....

Answer 16

is it (-7,-16)

Answer 17

Multiply the first equation by negative two, add the equations together. That will give you the value for x, substitute to get the answer for y. Easy.

Answer 18

thanks

Answer 19

2x+y=12
-5x-y=-33
second to last one please help t
thanks agn animal and matricked

Answer 20

is it (7,-2)

Answer 21

5x-y=-3
15x-3y=-9
which one applys select all that do
no soulotion
indepedent
dependent
consistent
infinate
inconsisitent

Answer 22

infinite solurtions

Answer 23

Dependent, consistent. Dependent indicates infinitely many solutions. Since there is at least one solution, the system is consistent.

Answer 24

thanks
