Printable algebra worksheet for solving two-sided equations.

Sure! Let’s solve each of the 16 two-sided algebraic equations step by step. The goal is to isolate the variable x on one side of the equation.

1.) x + 142 = 16x + 7

Subtract x from both sides:
→ 142 = 15x + 7

Subtract 7 from both sides:
→ 135 = 15x

Divide by 15:
→ x = 9

✔ Answer: x = 9

---

2.) 8x = 2x - 6

Subtract 2x from both sides:
→ 6x = -6

Divide by 6:
→ x = -1

✔ Answer: x = -1

---

3.) 1 + 9x = 7 + 8x

Subtract 8x from both sides:
→ 1 + x = 7

Subtract 1:
→ x = 6

✔ Answer: x = 6

---

4.) -8x + 8 = 10 + 5 - 9x

Simplify right side: 10 + 5 = 15
→ -8x + 8 = 15 - 9x

Add 9x to both sides:
→ x + 8 = 15

Subtract 8:
→ x = 7

✔ Answer: x = 7

---

5.) 7x + 2 = -10x + 2

Add 10x to both sides:
→ 17x + 2 = 2

Subtract 2:
→ 17x = 0

→ x = 0

✔ Answer: x = 0

---

6.) 55 - x = 2x + 13

Add x to both sides:
→ 55 = 3x + 13

Subtract 13:
→ 42 = 3x

Divide by 3:
→ x = 14

✔ Answer: x = 14

---

7.) -3x - 4x = -8x + 1

Combine left side: -7x = -8x + 1

Add 8x to both sides:
→ x = 1

✔ Answer: x = 1

---

8.) 5 - 5x + 6 = 4 - 4x

Simplify left: 11 - 5x = 4 - 4x

Add 5x to both sides:
→ 11 = 4 + x

Subtract 4:
→ x = 7

✔ Answer: x = 7

---

9.) 7x - 5 = 9x + 9

Subtract 7x from both sides:
→ -5 = 2x + 9

Subtract 9:
→ -14 = 2x

Divide by 2:
→ x = -7

✔ Answer: x = -7

---

10.) -20 - 8x = 5x - 7

Add 8x to both sides:
→ -20 = 13x - 7

Add 7:
→ -13 = 13x

Divide by 13:
→ x = -1

✔ Answer: x = -1

---

11.) 100 - x = 6 + 11x + 10

Simplify right: 6 + 10 = 16 → 100 - x = 11x + 16

Add x to both sides:
→ 100 = 12x + 16

Subtract 16:
→ 84 = 12x

Divide by 12:
→ x = 7

✔ Answer: x = 7

---

12.) -5 + 5x = 10x + 4 - 6x

Simplify right: 10x - 6x = 4x → -5 + 5x = 4x + 4

Subtract 4x from both sides:
→ -5 + x = 4

Add 5:
→ x = 9

✔ Answer: x = 9

---

13.) x - 9 - 5x = 2 - 5x

Left side: -4x - 9 = 2 - 5x

Add 5x to both sides:
→ x - 9 = 2

Add 9:
→ x = 11

✔ Answer: x = 11

---

14.) 38 + 12x = 64 - x

Add x to both sides:
→ 38 + 13x = 64

Subtract 38:
→ 13x = 26

Divide by 13:
→ x = 2

✔ Answer: x = 2

---

15.) 3x - 10 = 4x - 8

Subtract 3x from both sides:
→ -10 = x - 8

Add 8:
→ x = -2

✔ Answer: x = -2

---

16.) x + 2 = 2x + 14

Subtract x from both sides:
→ 2 = x + 14

Subtract 14:
→ x = -12

✔ Answer: x = -12

---
