Question

will medal and fan xx

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

x + y = 6
x = y + 2

Answer 1

they both can

Answer 2

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

Answer 3

i think it might either be B or D

Answer 4

No, you're wrong.

Answer 5

You're gonna substitute y + 2 for x in the first equation.

Answer 6

neither one of those are it

Answer 7

That will get you:

x + y = 6

(y + 2) + y = 6

Answer 8

Nope.. xD @shortycme

Answer 9

So which option is it? @literally.kaylaa

Answer 10

OH! I get what you did there! cx Its c Thanks!! @iGreen

Answer 11

wait im gonna need you to explain it to me @iGreen cuz im confused now

Answer 12

Lol, yeah^. you basically plug y in to the first equation. but im going to let him explain cause he's better at it :)

Answer 13

The answer is C..because to solve the system of equations by substitution you have to put in x = (y + 2) in the first equation..because the second equation says that x = y + 2.

Therefore we can put (y + 2) in the second equation for x:

x + y = 6

(y + 2) + y = 6

Get it? @shortycme

Answer 14

oh i see now

Answer 15

I have one more question ^.^ but im not going to close this until he gets it . Lol cx

Answer 16

i got it you can close it now
