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

Question

1−3m
m, minus, 3m−3
minus, 8, m−8m
minus, 2, m−2m

Answer 1

To simplify the expression 3m + m - 6m, we combine like terms.

3m and m are like terms because they both contain the variable m to the first power. When we combine them, we add their coefficients:

3m + m = (3+1)m = 4m

Now we incorporate the -6m:

4m - 6m = (4-6)m = -2m

So the expression 3m + m - 6m simplifies to -2m.

Therefore, the equivalent expression is:

-2m
