Question

Solve by the elimination method
5x+2y=-7
7x-3y=17

Answer 1

let say u want to remove the y so they make them cancel out, i'm shock u still having problem

(5x+2y=-7 )(3)
(7x-3y=17 )(-2)

Answer 2

you add them up and you will get x alone

Answer 3

then simply plug in answer for x for either 1 of the 2 equation and find y

Answer 4

shouldn't be too hard just "combining equations" a more easier understandable definition for the more technical term elimination method

Answer 5

isolate one of the variables and then just solve

Answer 6

sorry is multiply (2) in the 2nd equation not -2

Answer 7

x= 13/19 is the wrong answer...I got that answer and it was wrong

Answer 8

why? where did you get that answer?

Answer 9

I go to online school and when we do our checkpoints it lets us do it until you get the right answer if you want, but before you move onto the next problem it tells you if you got the problem right or not.

Answer 10

x=13/29?

Answer 11

14+15 is 29

Answer 12

If I get the answer wrong 3 times it will give me the right answer but then I will gave to get a new problem and start all over.

Answer 13

I will give it to you hold on.

Answer 14

13/29, -134/29

Answer 15

I got the second part completely wrong...Now I have to start over with a whole new problem

Answer 16

let me try the second part

Answer 17

but do u understand that is just removing one of the variables away and solving for the other?

Answer 18

math is about the solving not the answer

Answer 19

if x =13/19

5x+2y=-7

5(13/19)+2y=-7
65/19 + 2y =-7
2y=-7-65/19
y=(-133-65)/38
y=-198/38


This is what I get. Now let my check if the solutions you have are right

Answer 20

x = 13/29 emunrradtvamg
you add 14 +15 wrong

Answer 21

lol

Answer 22

why dont you just shut up!!

Answer 23

it was a joke, i did mention it though, but you know it , jesus , she's been posting these question for quite a while

Answer 24

ok try to help her then. She is having trouble with that. Isnt that obvious?

Answer 25

Hey the answer you have is right!

Answer 26

15x+6y=-21
14x-6y=-34

29x=13
x=13/29

to find y

5(13/25)+2y=-7
65/29 + 2y =-7
2y=-7-65/29
y=(-203-65)/58
y=-134/29
