Show Answer Key & Explanations Step-by-step solution for: Simplifying by Collecting Like Terms (1) - Mathematics and Coding
Let's solve each expression in Part 1 by combining like terms. Like terms are terms that have the same variable raised to the same power. We'll add or subtract their coefficients.

1. $ 4f + 9f + 9f + 2f + 9f $



Add all the coefficients of $ f $:

$$
4 + 9 + 9 + 2 + 9 = 33
$$

So, $ 33f $

Answer: $ 33f $

---

2. $ 4u + 7u + 8u - 8u + 4u $



Add the coefficients:

$$
4 + 7 + 8 - 8 + 4 = 15
$$

So, $ 15u $

Answer: $ 15u $

---

3. $ -8i + 7i - 7i + 7i $



Add the coefficients:

$$
-8 + 7 - 7 + 7 = -1
$$

So, $ -i $

Answer: $ -i $

---

4. $ 7l - 3l + 3l $



$$
7 - 3 + 3 = 7
$$

So, $ 7l $

Answer: $ 7l $

---

5. $ 8t + 5t - 7t - 4t - 8t $



Add the coefficients:

$$
8 + 5 - 7 - 4 - 8 = (13) - (19) = -6
$$

So, $ -6t $

Answer: $ -6t $

---

6. $ -5e + 4e + 9e + 2e - 3e $



Add the coefficients:

$$
-5 + 4 + 9 + 2 - 3 = (-5 - 3) + (4 + 9 + 2) = -8 + 15 = 7
$$

So, $ 7e $

Answer: $ 7e $

---

7. $ -6y - 7y + 9y + 4y $



Add the coefficients:

$$
-6 - 7 + 9 + 4 = (-13) + 13 = 0
$$

So, $ 0 $

Answer: $ 0 $

---

8. $ 4c + 6c + 4c $



$$
4 + 6 + 4 = 14
$$

So, $ 14c $

Answer: $ 14c $

---

9. $ 5j + 5j + 6j - 8j + 4j $



$$
5 + 5 + 6 - 8 + 4 = (16) - 8 = 8
$$

So, $ 8j $

Answer: $ 8j $

---

10. $ 2b - 10b - 4b + 9b + 2b $



$$
2 - 10 - 4 + 9 + 2 = (2 + 9 + 2) - (10 + 4) = 13 - 14 = -1
$$

So, $ -b $

Answer: $ -b $

---

11. $ 10t - 4t $



$$
10 - 4 = 6
$$

So, $ 6t $

Answer: $ 6t $

---

12. $ -5p + 3p $



$$
-5 + 3 = -2
$$

So, $ -2p $

Answer: $ -2p $

---

13. $ -9w - 6w $



$$
-9 - 6 = -15
$$

So, $ -15w $

Answer: $ -15w $

---

14. $ 8h + 9h - 10h $



$$
8 + 9 - 10 = 7
$$

So, $ 7h $

Answer: $ 7h $

---

Final Answers:



1. $ 33f $
2. $ 15u $
3. $ -i $
4. $ 7l $
5. $ -6t $
6. $ 7e $
7. $ 0 $
8. $ 14c $
9. $ 8j $
10. $ -b $
11. $ 6t $
12. $ -2p $
13. $ -15w $
14. $ 7h $
