## 🔢 Problem-by-Problem Solutions:
---
Step 1: Subtract 3x from both sides
→ x – 5 = 17
Step 2: Add 5 to both sides
→ x = 22
✔ Answer: x = 22
---
Step 1: Subtract 3x from both sides
→ -2 = 12x – 10
Step 2: Add 10 to both sides
→ 8 = 12x
Step 3: Divide by 12
→ x = 8/12 = 2/3
✔ Answer: x = 2/3
---
Step 1: Subtract 4x from both sides
→ 4x – 12 = 17
Step 2: Add 12 to both sides
→ 4x = 29
Step 3: Divide by 4
→ x = 29/4
✔ Answer: x = 29/4
---
*(Note: 9x + 5x = 14x)*
So: –8x – 81 = 14x + 1
Step 1: Add 8x to both sides
→ –81 = 22x + 1
Step 2: Subtract 1 from both sides
→ –82 = 22x
Step 3: Divide by 22
→ x = –82/22 = –41/11
✔ Answer: x = –41/11
---
*(Simplify right side: 1 + 17x)*
Left side: –12 + 18x
So: –12 + 18x = 1 + 17x
Step 1: Subtract 17x from both sides
→ –12 + x = 1
Step 2: Add 12 to both sides
→ x = 13
✔ Answer: x = 13
---
Left: 8x – 3x – 9 = 5x – 9
Right: 6x – 3
So: 5x – 9 = 6x – 3
Step 1: Subtract 5x from both sides
→ –9 = x – 3
Step 2: Add 3 to both sides
→ –6 = x
✔ Answer: x = –6
---
Left: –6x – 15
Right: 3 – 12x – 38 = –12x – 35
So: –6x – 15 = –12x – 35

→ 7x + 31 = 19
Step 2: Subtract 31
→ 7x = –12
Step 3: Divide by 7
→ x = –12/7
✔ Answer: x = –12/7
---
Multiply entire equation by 2 to eliminate fractions:
→ 6x = x – 1
Step 1: Subtract x
→ 5x = –1
Step 2: Divide by 5
→ x = –1/5
✔ Answer: x = –1/5
---
Multiply entire equation by 4 to eliminate denominators:
→ 2x + 8 = 3x – 4
Step 1: Subtract 2x
→ 8 = x – 4
Step 2: Add 4
→ x = 12
✔ Answer: x = 12
---
First, combine terms on the right:
→ 1/3 x = (1/6 – 2)x = (1/6 – 12/6)x = –11/6 x
Now: 1/3 x = –11/6 x
Add 11/6 x to both sides:
→ 1/3 x + 11/6 x = 0
Convert 1/3 to 2/6:
→ 2/6 x + 11/6 x = 13/6 x = 0
→ x = 0
✔ Answer: x = 0
---

## 💡 Tips for Success:
- Always simplify both sides first.
- Use LCD to eliminate fractions early.
- Double-check by plugging your answer back into the original equation.
- If you get “x = x” → infinite solutions; if contradiction → no solution.
