Question

Sherry uses the steps below to solve the equation x+(-8)=3x+6 .

Step 1 Add 1 negative x-tile to both sides and create zero pairs
Step 2 Add 8 positive unit tiles to both sides and create zero pairs.
Step 3 Divide the 14 unit tiles evenly among the 2 x-tiles.
Step 4 The solution is x=7

what was sherrys error?

What is Sherry’s error?
In step 1, she should have added 3 negative x-tiles to both sides.
In step 2, she should have added 6 negative unit tiles to both sides.
In step 3, she did not divide the tiles evenly.
In step 4, she should have found the solution mc022-3.jpg.

Answer 1

what's the last option?

Answer 2

what's the solution ?? `mc022-3.jpg` this is the link which is not working.

Answer 3

IDK. It was there when the question was posted.

Answer 4

yeah that's why I was trying to clarify..
but why did you say the last one is correct when you don't know what it is.

Answer 5

Step 2 is where the error is. x-8 = 3x+6
-8=2x+6
you don't add 8 other wise you get 0=2x+14. You want to isolate x
