Steps provided by the student:
1. Start with 8x-2(4+3x)
2. Use the distributive property to simplify -2(4+3x) to -8-6x
3. Combine like terms to get 8x+(-8-6x)
4. Simplify further by adding the like terms to get 2x-8
5. Simplify completely to get 3x-8
The student's claim is incorrect. The expression 8x-2(4+3x) simplifies to 2x-8, not 3x.
A student claims that 8x-2(4+3x) is equivalent to 3x The student's steps are shown below.

Would 2x -8 be -6 then?
No, 2x - 8 is not equal to -6.
The expression 2x - 8 cannot be simplified further unless more information about the value of 'x' is given. It is a simplified form of the original expression 8x - 2(4 + 3x).
The expression -6 is not obtained anywhere in the given steps or the simplified expression.
