Answer:

just substitute y+2 instead of x in the 2nd equation

y+2+y=10

2y+2=10

2y=10-2

2y=8

y=4

to get x we use equation 1

since we have got the y value

x=4+2

x=6

So your answer will be A in the method (x,y)

Answer: C. No solution

Step-by-step explanation:

  1. [tex]x=y+2\\x+y=10[/tex]
  2. So you put the x= equation in for x
  3. (y+12) + y = 10
  4. Then combine like terms
  5. 2y + 12 = 10
  6. Then subtract 12 from both sides
  7. 2y = -2
  8. Then divide by 2
  9. y=-1
  10. Plug y into one of the equations.
  11. x = -1 + 2
  12. x= 1

You'll find that it's impossible for ( 1, -1) to be the answer because 1+(-1 ) ≠ 10

So there is no solution.
