Which of the following expressions are not equivalent to the expression 2x + 2 - 5x + 7 - 3? Select all that apply.

Answer 1

The expression we start with is 2x + 2 - 5x + 7 - 3.

Let's simplify it:

First, combine like terms:

2x - 5x = -3x.

2 - 3 = -1.

So, our simplified expression is -3x - 1.

Now we can check the given expressions:

A) -1 - 3x

This expression is equivalent to our simplified expression -3x - 1, so it is equivalent to the original expression.

B) -3x -1

This expression is equivalent to our simplified expression -3x - 1, so it is equivalent to the original expression.

C) 4 - 8x

This expression is not equivalent to our simplified expression -3x - 1, so it is not equivalent to the original expression.

D) 2 - 7x

This expression is not equivalent to our simplified expression -3x - 1, so it is not equivalent to the original expression.

Therefore, the expressions that are not equivalent to 2x + 2 - 5x + 7 - 3 are C) 4 - 8x and D) 2 - 7x.
