Studdy Solution

STEP 1

Assumptions
1. We are given a simple algebraic expression: 15m+9m-15m + 9m.
2. We need to simplify the expression by combining like terms.

STEP 2

Identify like terms in the expression. Like terms are terms that contain the same variable raised to the same power.
In the given expression, 15m-15m and 9m9m are like terms because they both contain the variable mm raised to the first power.

STEP 3

Combine the like terms by adding their coefficients. The variable mm will remain unchanged.
15m+9m=(15+9)m-15m + 9m = (-15 + 9)m

STEP 4

Perform the addition of the coefficients.
15+9=6-15 + 9 = -6

STEP 5

Now, multiply the result from the previous step by the variable mm.
6m-6m

STEP 6

The simplified form of the expression 15m+9m-15m + 9m is 6m-6m.
The solution to the problem is 6m-6m.
