Simplify the expression by combining any like terms.
m+3m-2m-9=
2m-9
To simplify the expression by combining like terms, we can add or subtract the coefficients of the variables that are the same.
The given expression is:
m + 3m - 2m - 9
First, let's combine the "m" terms:
m + 3m - 2m = (1 + 3 - 2)m = 2m
Now, the simplified expression becomes:
2m - 9
To simplify the expression, we need to combine like terms, which means adding or subtracting terms that have the same variable and exponent.
Given the expression:
m + 3m - 2m - 9
Let's combine the like terms:
m + 3m - 2m - 9 = (1m + 3m - 2m) - 9
To combine the terms with the same variable "m", we add their coefficients:
m + 3m = 4m
So the expression becomes:
4m - 2m - 9
Next, we combine the two remaining like terms, -2m - 9:
-2m - 9 = (-2m) - 9
Now, there are no more like terms to combine, so we bring down the expression as it is:
4m - 2m - 9
Therefore, the simplified expression is 2m - 9.
