tell whether this pair of expressions is equivalent.

1/3x+5-2x and 5-5/3x

To determine whether the pair of expressions is equivalent, we need to simplify both and see if they result in the same expression.

1/3x + 5 - 2x:

First, we can combine like terms, so we have:

(-2x + 1/3x) + 5

Next, we can combine the x terms:

(-2 + 1/3)x + 5

To combine the x terms further, we need a common denominator, which is 3:

(-6/3 + 1/3)x + 5

-5/3x + 5

So, the first expression simplifies to -5/3x + 5.

Now let's simplify the second expression:

5 - 5/3x

The second expression is already simplified.

So, the first expression -5/3x + 5 is not equivalent to the second expression 5 - 5/3x.
