Answer:
Step-by-step explanation:
First, you need to find the GCF of both denominators.
That would be 21.
You would need to multiple the 7 in 4/7 by 3, to get to 21. That means you would also have to multiply 3 by the 4. You should get 12/21.
Do you same thing to 1/3.
After that you should get the 2 factions, 12/21 and 7/21
12/21 + 7/21 = 19/21
There isn't anyway to simplify it, meaning the final answer is 19/21.

Answer:
x² - x - 6
Step-by-step explanation:
Step 1: Write expression
(5x² + 2x - 5) - (3x² + 3x + 1)
Step 2: Distribute negative
5x² + 2x - 5 - 3x² - 3x - 1
Step 3: Combine like terms (x²)
2x² + 2x - 5 - 3x - 1
Step 4: Combine like terms (x)
x² - x - 5 - 1
Step 5: Combine like terms (constants)
x² - x - 6
