Answer 1

@JuanitaM

Answer 2

@RoseDryer can you help?

Answer 3

how did you get (1,-1)?
i got a different answer, can you show me your solution?

Answer 4

yes

Answer 5

can you show it to me then?

Answer 6

give me a second i wrote it in a paper trying to find it

Answer 7

ok

Answer 8

2x + y = 3
-3x + 4y = 1
-x + 5y = 4
and replace 1 by x and get
- 1 + 5y = 4
+1 +1
5y = 5
/5 /5
y = 1 and x = 1 <<<< oh is that the answer?

Answer 9

hum.... i don't think the problem is asking about that Substitution
2x + y =3 and -3x+4y = 1 , if you move 2x from the first eq. you get y = 3 - 2x now you can substitute y in the second eq with y = 3-2x

Answer 10

can i show you the answer choices and you tel me what you think it is?

Answer 11

where did you get -x + 5y = 4???

Answer 12

i think shine added the two eqs

Answer 13

i put them together the two equations together

Answer 14

are there three equations?

Answer 15

aahh.. ok..

Answer 16

follow @i3lue 's instructions, that's the right steps for substitution..

Answer 17
