Question

Please Help! Solve using elimination( the addition method)
{10/3x+4y=-4
{5x+6y=-6

Answer 1

multiply the first one by 3 and the second one by -2 and then your x's cancel out and then combine ur 2 y's together

Answer 2

okay. thanks! could you double check my answer once i get it?

Answer 3

sure

Answer 4

okay so when i went to mulitply the 10/3. do i mulitply the 10 and 3?

Answer 5

because i got 10x+12y=-12
-10x-12y=12

Answer 6

when you multiply the 10/3 by 3 the three's cancel each other out and you will be left with 10

Answer 7

but since that gave you that 0=0 try eliminating the y's and see what you get

Answer 8

ok

Answer 9

are you sure that you wrote the problems down right because when you eliminate the y you still end up with the same equation both spots

Answer 10

i still get 0=0

Answer 11

yes i did.

Answer 12

you should get x=0 and y=-1

Answer 13

okay. can you explain how you got those numbers please?

Answer 14

see the thing is with this equation you can have an unlimited amount of solutions so since you found that when deleting the x out of the equation you get 0 then if you sub the 0 back in for x, you should then get y=-1, but if you eliminate y out you get 0 then if you sub that 0 back in you will get an answer other than 0 for x

Answer 15

oh okay. thank you for your help!

Answer 16

yep no problem glad i could help you!
