Answer 1

You know what x is equal to, so plug that bad boy into the other equation.

Answer 2

x = 8

Answer 3

@KarieMonsrerrxD you shouldn't give out answers, ESPECIALLY when they are wrong!

Answer 4

lmao idc x would be 8 tho right ? because 8 - 2 is 6

Answer 5

Nope nope nope.

Answer 6

oh , i tryed lol

Answer 7

x - y = 6

(y+2) - y = 6 ... replace x with y+2 (since x = y+2)

y+2 - y = 6

I'll let you finish

Answer 8

no solution

Answer 9

ohhhhhh

Answer 10

hey magan

Answer 11

lol

Answer 12

When you have x = y + 2 and you plug into x - y = 6 you get:

(y + 2) - y = 6 ==> 2 = 6 (which can't be).

If you do it the other way with y = x - 2 you would get:

x - ( x - 2) = 6 ==> 2 = 6 (which also can't be).

Therefore, there is no solution.
