Math worksheet providing answers to simple equations, solving for each unknown variable.

Let’s solve each equation one by one. We’ll find the value of the unknown letter in each case.

---

1. 6 = 2 + u
Subtract 2 from both sides:
6 - 2 = u → u = 4

---

2. 5 = k - 4
Add 4 to both sides:
5 + 4 = k → k = 9

---

3. (-16) = (-9) - w
We can rewrite this as:
-16 = -9 - w
Add 9 to both sides:
-16 + 9 = -w → -7 = -w
Multiply both sides by -1:
w = 7

---

4. (-7) + x = (-5)
Add 7 to both sides:
x = -5 + 7 → x = 2

---

5. 8 = r + 4
Subtract 4 from both sides:
8 - 4 = r → r = 4

---

6. 3 + n = 7
Subtract 3 from both sides:
n = 7 - 3 → n = 4

---

7. v + (-3) = (-10)
This is the same as:
v - 3 = -10
Add 3 to both sides:
v = -10 + 3 → v = -7

---

8. (-4) + q = (-3)
Add 4 to both sides:
q = -3 + 4 → q = 1

---

9. 9 = j + 7
Subtract 7 from both sides:
j = 9 - 7 → j = 2

---

10. (-3) = (-6) - n
Rewrite:
-3 = -6 - n
Add 6 to both sides:
-3 + 6 = -n → 3 = -n
Multiply both sides by -1:
n = -3

---

11. (-14) = r - 6
Add 6 to both sides:
-14 + 6 = r → r = -8

---

12. 5 = 1 + d
Subtract 1 from both sides:
d = 5 - 1 → d = 4

---

13. (-2) - k = 4
Rewrite:
-2 - k = 4
Add 2 to both sides:
-k = 6
Multiply by -1:
k = -6

---

14. 9 + n = 11
Subtract 9 from both sides:
n = 11 - 9 → n = 2

---

15. (-10) = n - 8
Add 8 to both sides:
-10 + 8 = n → n = -2

---

16. (-5) = (-3) - n
Rewrite:
-5 = -3 - n
Add 3 to both sides:
-5 + 3 = -n → -2 = -n
Multiply by -1:
n = 2

---

17. (-9) = s + (-4)
Same as:
-9 = s - 4
Add 4 to both sides:
s = -9 + 4 → s = -5

---

18. 0 = f + 7
Subtract 7 from both sides:
f = 0 - 7 → f = -7

---

19. (-4) - s = 0
Rewrite:
-4 - s = 0
Add 4 to both sides:
-s = 4
Multiply by -1:
s = -4

---

20. b + 4 = 12
Subtract 4 from both sides:
b = 12 - 4 → b = 8

---

Final Answer:
u = 4, k = 9, w = 7, x = 2, r = 4, n = 4, v = -7, q = 1, j = 2, n = -3, r = -8, d = 4, k = -6, n = 2, n = -2, n = 2, s = -5, f = -7, s = -4, b = 8
