Understanding the Formulas
1. Linear Equation Formula
ax+b=c
To solve for x:
x=ac−b
2. Simple Equation Formula
x+b=c
To solve for x:
x=c−b
Step-by-Step Example Calculations
Example 1: Linear Equation
Given:
- a = 2
- b = 4
- c = 10
Solution:
x = (10 − 4) ÷ 2
x = 6 ÷ 2
x = 3
Result: x = 3
Example 2: Simple Equation
Given:
- b = 5
- c = 12
Solution:
x = 12 − 5
x = 7
Result: x = 7
Quick Reference Table
| Equation Type | a | b | c | Formula Used | Value of x |
|---|---|---|---|---|---|
| Linear | 2 | 4 | 10 | (c − b) ÷ a | 3 |
| Linear | 5 | 3 | 23 | (c − b) ÷ a | 4 |
| Simple | — | 5 | 12 | c − b | 7 |
| Simple | — | 8 | 20 | c − b | 12 |
| Linear | 3 | 6 | 15 | (c − b) ÷ a | 3 |
