@AnswerMyQuestions can u help her
i have togo :)

Answer 5

ok thank you

Answer 6

You have togo?

Answer 7

I was afk :O

Answer 8

Multiply -6 to the second equation so when you add them, the x-values cancel out.

Answer 9

*s values

Answer 10

s+2t=6
6s-4t=4

First multiply the first equation by 2 on both sides
Post your answer here

Answer 11

2s+2t=12
like that?

Answer 12

is it 2 or 4 in the second number

Answer 13

yes - that is the idea - but it's 4

Answer 14

okay and now what do i do

Answer 15

now ADD the correct new equation to the second equation:
2s+4t=12
6s-4t=4

Answer 16

8s-0=12
thats what it gives me

Answer 17

not quite - you need to add the right hand side too

Answer 18

which right hand side

Answer 19

the 12 and the 4

Answer 20

ohh ok

Answer 21

so

8s = 16

what is s?

Answer 22

2

Answer 23

good

so this is know as 'elimimation' - we eliminated t by adding the equations together and we now know that s = 2

Answer 24

thank you for helping me

Answer 25

so now we need to find t

take one of the original equations
6s-4t=4

and put the value s=2 in it

rewrite it when s=2
