Question

Which equation shows the substitution method being used to solve the system of linear equations?

x + y = 6
x = y + 2


A)) x + y = y + 2
B)) x + (y + 2) = 6
C)) x = (x – 6) + 2
D)) (y + 2) + y = 6

Answer 1

So basically they want to know what is the next step in solving that substitution.


So we have x=y+2

we want to substitute the value we get for x into x+y=6

Answer 3

its c, becuase you can substute the value of x into the equation

Answer 4

Actually C is wrong.

Answer 5

explain @TheSmartOne

Answer 6

x + y = 6
x = y + 2

since x= y+2
we could plug that into x+y=6

So

x+y=6
(y+2)+y=6

Answer 7

c. x= (x-6)+2

Answer 8

your solution of course will work @TheSmartOne

Answer 9

mine won t work!

Answer 10

What I just proved -_-

Answer 11

because I have x =x

Answer 12

and that is why you r @TheSmartOne
