Which expression is equivalent to 3, m, plus, m, minus, 6, m3m+m−6m?

Answer 1

It appears that there is a bit of confusion in the expression provided. Let me try to parse it out correctly:

The expression provided is "3, m, plus, m, minus, 6, m". If we remove the commas and put it in mathematical terms, it looks like this:

3m + m - 6m

To simplify this expression, we just combine like terms. All terms are multiples of 'm', so we can add and subtract the coefficients.

(3m + m) - 6m
= 4m - 6m

Now, we subtract 6m from 4m:

4m - 6m = -2m

The equivalent simplified expression is:

-2m

The additional "3m + m − 6m" at the end of your message may have been a repetition of the expression, but the equivalent for the expression given is simply -2m.
