To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The expression is . We identify like terms and consider the fraction denominators.
Step 2: Combine the terms involving :
.
We simplify to . Therefore, this becomes .
Step 3: Include the other terms that cannot be further simplified as they are alone. Thus, the entire expression becomes:
.
This can be rearranged to , where each part is shown in terms of mixed numbers for clearer expression matching.
Therefore, the solution to the problem is .
Are the expressions the same or not?
\( 20x \)
\( 2\times10x \)
Like terms have the same variable raised to the same power. In this problem, and are like terms because both have m as the variable.
Because they have different variables! The term has variable n, while the other terms have variable m. You can only combine terms with identical variables.
When denominators are the same, just add the numerators: . Then simplify if possible!
Mixed numbers like are often easier to understand than improper fractions like . Plus, the answer choices use mixed number format!
That's perfectly fine! You could write from the start. Either way works - just be consistent with your fraction simplification.
