2x + 2+ 2x + 3x – 8
4 + 7x – 2
–2 + 5x + 2x – 4
8x – x – 6

4 + 7x – 2

Step-by-step explanation:

Equivalent Expressions

Let's find out which expressions are equivalent by simplifying them. One of the expressions should be not equivalent to the other three.

Simplifying

Now for the second expression

The third expression simplifies to

Finally, this is the simplification for the expression

As seen, the only expression not equivalent to the other three is 4 + 7x – 2
