Answer 2

are you in anon?

Answer 3

no solution of these equations..!!! but can have if a tranformation eq from Y to y and X to x is given..!!!

Answer 4

6-x=x-2
-6 -6
-x =x+4
-x -x
-2x=4
--------
-2 -2

x =-2


y=mx+b
y=-2x+b
can u do the rest from there or do you need more help??

Answer 5

Im confused @Eli_Moses ?

Answer 6

which part

Answer 7

y=mx+b and y=-2x+b

Answer 8

basically you're just substituting x and y in both equations to find the coordinate that can be the solution for both equations.
C

just input both equations and find the point of intersection
point of intersection=solution

Answer 9

Ok thanks what's C^^

Answer 10

u'll find out

Answer 13

You believe the answer is C?
You can confirm whether it is or not by just plugging in the coordinate into each equation.
C) (x, y) = (4, 2)
y = 6 - x and y = x - 2 x=4, y=2
2 = 6 - 4 and 2 = 4 - 2.
Are both of these equations true?

Answer 14

No

Answer 15

Which one looks wrong?
2 = 6 - 4 simplify the right side
2 = 2 That is a true statement; we can't argue that 2 equals itself!

Answer 16

yeah ur right

Answer 17

And for 2 = 4 - 2
We simplify 4 - 2 and get 2 as well. 2 = 2 again, and so (C) does work to solve this system!

Answer 18

thanks
