Question

SOMEONE CHECK MY ANSWER PLEASE

Answer 1

Explain, in complete sentences, how you would use the elimination method to solve the following system of equations and provide the solution to the system.

5x - 9y = -16
2x + 6y = -16

Answer 2

5x - 9y = -16<-- multiply by -2
2x + 6y = -16<--- multiply by 5

Answer 3

after doing the math it is
-10x+18y=32
10x+30y=-80
ADD THEM

Answer 4

48y=48
y=1
PLUG IN Y

Answer 5

But after plugging in y the equations
x=2 and x=5
shouldnt they be the same? because then when i plug x into the equation with y it doesnt work out right

Answer 6

5(2)-9(1)=-16 no
2(5)+6(1)=-16 no

Answer 7

you made an error when you got to `48y=48`

it should be `48y=-48`. Notice how the 48 on the right side is negative

Answer 8

so its -1

Answer 9

yes y = -1

Answer 10

so 5x-9(-1)=-16
5x+9=-16
5x=-7
x=-7/5

Answer 11

2x+6(-1)=-16
2x+6=-16
2x=-22
x=-11

Answer 12

subtract 9 from both sides to get

5x+9=-16
5x+9-9=-16-9
5x = -25

Answer 13

I forgot they were both negatives go you would add them

Answer 14

so x=-5 and x=-11

Answer 15

it should just be x = -5

Answer 16

2x+6(-1)=-16
2x-6 = -16
2x-6+6 = -16+6
2x = -10
x = -5

Answer 17

-16+6 is 10 im sorry

Answer 18

Wow i am bad with signs tonight LOL

Answer 19

Possibly a sign of fatigue, sorry I couldn't help the pun...

Answer 20

so the solution would be (-5,-1)?

Answer 21

so in the end, x = -5 and y = -1, yes

Answer 22

hahah! very punny

Answer 23

Thank you Jim! I appreciate it!

Answer 24

you're welcome
