Let's solve each equation one by one and then match them with the correct answers:

1. $4x = 40$

   • Divide both sides by 4: $x = \frac{40}{4} = 10$

2. $x + 5 = 10$

   • Subtract 5 from both sides: $x = 10 - 5 = 5$

3. $x + 8 = 11$

   • Subtract 8 from both sides: $x = 11 - 8 = 3$

4. $x - 11 = 16$

   • Add 11 to both sides: $x = 16 + 11 = 27$

5. $x - 9 = 21$

   • Add 9 to both sides: $x = 21 + 9 = 30$

6. $x + 3 = 32$

   • Subtract 3 from both sides: $x = 32 - 3 = 29$

7. $6x = 42$

   • Divide both sides by 6: $x = \frac{42}{6} = 7$

8. $x + 14 = 46$

   • Subtract 14 from both sides: $x = 46 - 14 = 32$

9. $8x = -32$

   • Divide both sides by 8: $x = \frac{-32}{8} = -4$

10. $x + 4 = 64$

    • Subtract 4 from both sides: $x = 64 - 4 = 60$

Solutions and Matching

1. $x = 10$
2. $x = 5$
3. $x = 3$
4. $x = 27$
5. $x = 30$
6. $x = 29$
7. $x = 7$
8. $x = 32$
9. $x = -4$
10. $x = 60$

These match with the given answers:

• $x = 10$ for equation 1
• $x = 5$ for equation 2
• $x = 3$ for equation 3
• $x = 27$ for equation 4
• $x = 30$ for equation 5
• $x = 29$ for equation 6
• $x = 7$ for equation 7
• $x = 32$ for equation 8
• $x = -4$ for equation 9
• $x = 60$ for equation 10
