<u>Equivalent Expressions</u>
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
