Solving algebraic equations worksheets | Worsheets library - Free Printable

Let's solve each of the 20 basic algebra equations from the worksheet step by step. The goal is to solve for the variable $ x $ in each equation, and express the answer as "$ x = $" (e.g., $ x = 5 $).

---

1) $ x + 12 = 14 $

Subtract 12 from both sides:
$ x = 14 - 12 $
$ x = 2 $

✔ Answer: $ x = 2 $

---

2) $ 11 + x = 15 $

Subtract 11 from both sides:
$ x = 15 - 11 $
$ x = 4 $

✔ Answer: $ x = 4 $

---

3) $ x - 5 = 6 $

Add 5 to both sides:
$ x = 6 + 5 $
$ x = 11 $

✔ Answer: $ x = 11 $

---

4) $ 2 + x = 8 $

Subtract 2 from both sides:
$ x = 8 - 2 $
$ x = 6 $

✔ Answer: $ x = 6 $

---

5) $ x - 3 = 2 $

Add 3 to both sides:
$ x = 2 + 3 $
$ x = 5 $

✔ Answer: $ x = 5 $

---

6) $ x - 6 = 6 $

Add 6 to both sides:
$ x = 6 + 6 $
$ x = 12 $

✔ Answer: $ x = 12 $

---

7) $ 7 + x = 14 $

Subtract 7 from both sides:
$ x = 14 - 7 $
$ x = 7 $

✔ Answer: $ x = 7 $

---

8) $ 12 - x = 7 $

We want to isolate $ x $. First, subtract 12 from both sides:
$ -x = 7 - 12 $
$ -x = -5 $
Multiply both sides by -1:
$ x = 5 $

✔ Answer: $ x = 5 $

---

9) $ 5 + x = 9 $

Subtract 5 from both sides:
$ x = 9 - 5 $
$ x = 4 $

✔ Answer: $ x = 4 $

---

10) $ x - 10 = 2 $

Add 10 to both sides:
$ x = 2 + 10 $
$ x = 12 $

✔ Answer: $ x = 12 $

---

11) $ x + 6 = 14 $

Subtract 6 from both sides:
$ x = 14 - 6 $
$ x = 8 $

✔ Answer: $ x = 8 $

---

12) $ 7 + x = 10 $

Subtract 7 from both sides:
$ x = 10 - 7 $
$ x = 3 $

✔ Answer: $ x = 3 $

---

13) $ 10 - x = 7 $

Subtract 10 from both sides:
$ -x = 7 - 10 $
$ -x = -3 $
Multiply both sides by -1:
$ x = 3 $

✔ Answer: $ x = 3 $

---

14) $ 8 + x = 15 $

Subtract 8 from both sides:
$ x = 15 - 8 $
$ x = 7 $

✔ Answer: $ x = 7 $

---

15) $ 8 - x = 1 $

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

✔ Answer: $ x = 7 $

---

16) $ x + 10 = 14 $

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

✔ Answer: $ x = 4 $

---

17) $ x - 3 = 8 $

Add 3 to both sides:
$ x = 8 + 3 $
$ x = 11 $

✔ Answer: $ x = 11 $

---

18) $ x + 7 = 9 $

Subtract 7 from both sides:
$ x = 9 - 7 $
$ x = 2 $

✔ Answer: $ x = 2 $

---

19) $ x + 7 = 19 $

Subtract 7 from both sides:
$ x = 19 - 7 $
$ x = 12 $

✔ Answer: $ x = 12 $

---

20) $ x + 2 = 10 $

Subtract 2 from both sides:
$ x = 10 - 2 $
$ x = 8 $

✔ Answer: $ x = 8 $

---
