Part 2:
Explain which method you chose to solve the system and why you felt it was the best choice.

Answer 1

FIND Y IN TERM OF X FROM EQUATION 1

Answer 2

huh...?

Answer 3

PLUG IN THAT VALUE INTO SECOND EQUATION

Answer 4

i dont know what you mean?

Answer 5

Y EQUAL WHAT FROM FIRST EQUATION?

Answer 6

y=10+x...?

Answer 7

NO Y=X-10

Answer 8

how..?

Answer 9

ADD PLUS Y TO BOTH SIDE
-10 FROM BOTH SIDE

Answer 10

why are you typing in all caps???

and that makes no since...

Answer 11

wouldnt you solve it like this though?

x-y=10
+y +y
--------
x=10+y

then substitute y into the second equation

Answer 12

y=?

Answer 13

y=-18?

Answer 14

now y=x-10

Answer 15

would x=28...?

Answer 16

2x+x-10=2

Answer 17

3x=12
x=4

Answer 18

you confuse me :/

Answer 19

get y from first equation
plug in that y into the second
thast it

Answer 20

you still confuse me.... lol sorry

Answer 21

x-y=10 what is y?

Answer 22

i solved for x for the first equation....

Answer 23

x-y=10
+y +y
------
x=10+y


2*10+y=2

20+y=2
-20 -20
--------
y=-18


2x-(-18)=10
+18 +18
------------
2x=28
/2 /2
-----
x=14

(14,-18)<==ANSWER
right??
