Practice solving for x with this printable one-step equations worksheet designed for middle school math students.

Let's solve each one-step equation step by step and check the solution.

---

🔹 1. $ x + 5 = 10 $

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

Check:
$$
5 + 5 = 10 \quad \text{✓ True}
$$

✔ Answer: $ x = 5 $

---

🔹 2. $ 6x = 42 $

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

Check:
$$
6 \times 7 = 42 \quad \text{✓ True}
$$

✔ Answer: $ x = 7 $

---

🔹 3. $ x - 6 = 9 $

Solve:
Add 6 to both sides:
$$
x = 9 + 6 = 15
$$

Check:
$$
15 - 6 = 9 \quad \text{✓ True}
$$

✔ Answer: $ x = 15 $

---

🔹 4. $ x \div 6 = 10 $

Solve:
Multiply both sides by 6:
$$
x = 10 \times 6 = 60
$$

Check:
$$
60 \div 6 = 10 \quad \text{✓ True}
$$

✔ Answer: $ x = 60 $

---

🔹 5. $ 14 = 2x $

Solve:
Divide both sides by 2:
$$
x = \frac{14}{2} = 7
$$

Check:
$$
2 \times 7 = 14 \quad \text{✓ True}
$$

✔ Answer: $ x = 7 $

---

🔹 6. $ 20 = x + 7 $

Solve:
Subtract 7 from both sides:
$$
x = 20 - 7 = 13
$$

Check:
$$
13 + 7 = 20 \quad \text{✓ True}
$$

✔ Answer: $ x = 13 $

---

🔹 7. $ 16 = x - 2 $

Solve:
Add 2 to both sides:
$$
x = 16 + 2 = 18
$$

Check:
$$
18 - 2 = 16 \quad \text{✓ True}
$$

✔ Answer: $ x = 18 $

---

🔹 8. $ x + 7 = 8 $

Solve:
Subtract 7 from both sides:
$$
x = 8 - 7 = 1
$$

Check:
$$
1 + 7 = 8 \quad \text{✓ True}
$$

✔ Answer: $ x = 1 $

---

🔹 9. $ 5 = x \div 2 $

Solve:
Multiply both sides by 2:
$$
x = 5 \times 2 = 10
$$

Check:
$$
10 \div 2 = 5 \quad \text{✓ True}
$$

✔ Answer: $ x = 10 $

---

🔹 10. $ x + 10 = 14 $

Solve:
Subtract 10 from both sides:
$$
x = 14 - 10 = 4
$$

Check:
$$
4 + 10 = 14 \quad \text{✓ True}
$$

✔ Answer: $ x = 4 $

---

🔹 11. $ 5x = 45 $

Solve:
Divide both sides by 5:
$$
x = \frac{45}{5} = 9
$$

Check:
$$
5 \times 9 = 45 \quad \text{✓ True}
$$

✔ Answer: $ x = 9 $

---

🔹 12. $ x - 9 = 10 $

Solve:
Add 9 to both sides:
$$
x = 10 + 9 = 19
$$

Check:
$$
19 - 9 = 10 \quad \text{✓ True}
$$

✔ Answer: $ x = 19 $

---

🔹 13. $ 18 + x = 23 $

Solve:
Subtract 18 from both sides:
$$
x = 23 - 18 = 5
$$

Check:
$$
18 + 5 = 23 \quad \text{✓ True}
$$

✔ Answer: $ x = 5 $

---

🔹 14. $ 16x = 16 $

Solve:
Divide both sides by 16:
$$
x = \frac{16}{16} = 1
$$

Check:
$$
16 \times 1 = 16 \quad \text{✓ True}
$$

✔ Answer: $ x = 1 $

---

🔹 15. $ x + 7 = 7 $

Solve:
Subtract 7 from both sides:
$$
x = 7 - 7 = 0
$$

Check:
$$
0 + 7 = 7 \quad \text{✓ True}
$$

✔ Answer: $ x = 0 $

🎯 Key Concept:

One-step equations require only one operation (addition, subtraction, multiplication, or division) to solve for $ x $. The goal is to isolate the variable on one side of the equation.

Always check your answer by plugging it back into the original equation!
