Sure, let's solve each of the given linear equations step by step.

---

### **6. $$ 2d - 9 = -1 $$**

**Step 1:** Add 9 to both sides to isolate the term with $$ d $$.

$$
2d - 9 + 9 = -1 + 9
$$
$$
2d = 8
$$

**Step 2:** Divide both sides by 2 to solve for $$ d $$.

$$
d = \frac{8}{2} = 4
$$

**Solution:** $$ d = 4 $$

---

### **7. $$ 7m + 4 = -10 $$**

**Step 1:** Subtract 4 from both sides to isolate the term with $$ m $$.

$$
7m + 4 - 4 = -10 - 4
$$
$$
7m = -14
$$

**Step 2:** Divide both sides by 7 to solve for $$ m $$.

$$
m = \frac{-14}{7} = -2
$$

**Solution:** $$ m = -2 $$

---

### **8. $$ 3n - 6 = -15 $$**

**Step 1:** Add 6 to both sides to isolate the term with $$ n $$.

$$
3n - 6 + 6 = -15 + 6
$$
$$
3n = -9
$$

**Step 2:** Divide both sides by 3 to solve for $$ n $$.

$$
n = \frac{-9}{3} = -3
$$

**Solution:** $$ n = -3 $$

---

### **9. $$ 8p + 2 = 18 $$**

**Step 1:** Subtract 2 from both sides to isolate the term with $$ p $$.

$$
8p + 2 - 2 = 18 - 2
$$
$$
8p = 16
$$

**Step 2:** Divide both sides by 8 to solve for $$ p $$.

$$
p = \frac{16}{8} = 2
$$

**Solution:** $$ p = 2 $$

---

### **10. $$ 4q - 5 = 7 $$**

**Step 1:** Add 5 to both sides to isolate the term with $$ q $$.

$$
4q - 5 + 5 = 7 + 5
$$
$$
4q = 12
$$

**Step 2:** Divide both sides by 4 to solve for $$ q $$.

$$
q = \frac{12}{4} = 3
$$

**Solution:** $$ q = 3 $$
