which expressions are equivalent to 6 +(–x) + 2x + (–7) + 2x? check all that apply.
x + x + 6 – 7 + x
2x + 2 + x
3 – x + 2x – 4 + 2x
x – 1
x + 1

   3x-7+ 6

Step-by-step explanation:

Group the x factors together and write them iut in groued pairs witht the same type terms and dd them up to get 3x and just put in the 6 and -7.

The expression is 6-x+2x-7+2x which is equal to 3x+6-7 that can be written as x+x+6-7+x.

Hence, option A is the correct answer.

The given expression is 6+(-x)+2x+(-7)+2x.

Apply the BODMAS priority rule to the above expression.

To set the priorities of mathematical operations, the BODMAS is applied. BODMAS rule can be explained below:

Thus,

The expression is 6-x+2x-7+2x which is equal to 3x+6-7 that can be written as x+x+6-7+x.

Hence, option A is the correct answer.
