Let’s solve each equation step by step. We’re looking for the value of
x that makes each equation true.
---
1. Equation:
x + 23 = 90
To get x alone, we undo the “+23” by subtracting 23 from both sides:
→ x + 23 - 23 = 90 - 23
→ x = 67
✔

2. Equation:
x - 12 = 74
To get x alone, we undo the “-12” by adding 12 to both sides:
→ x - 12 + 12 = 74 + 12
→ x = 86
✔

3. Equation:
4x = 148
This means 4 times x equals 148. To get x alone, divide both sides by 4:
→ 4x ÷ 4 = 148 ÷ 4
→ x = 37
✔
*(Check: 4 × 37 = 148 — yes!)*
---
4. Equation:
x / 12 = 86
This means x divided by 12 equals 86. To get x alone, multiply both sides by 12:
→ (x / 12) × 12 = 86 × 12
→ x = 1032
✔
*(Check: 1032 ÷ 12 = 86 — yes!)*
---
Final Answer:
The solutions are:
x = 67, x = 86, x = 37, and x = 1032
