Click reset to clear inputs and start again.
Understanding the Formula
The calculator is based on the standard linear equation:
Equation Form:
ax+b=c
Step 1: Subtract b from both sides
ax=c−b
Step 2: Divide both sides by a
x=ac−b
Final Formula Used by Calculator:
x=ac−b
This is the core formula used to solve any 2-step linear equation.
Important Condition
The coefficient a cannot be zero, because division by zero is undefined in mathematics.
Example Calculation
Let’s understand this with a simple example:
Given Equation:
3x+6=18
Step 1: Identify values
- a = 3
- b = 6
- c = 18
Step 2: Apply formula
x=318−6 x=312
Final Answer:
x=4
Another Example
Equation:
5x−10=20
Step-by-step:
| Step | Calculation |
|---|---|
| a = 5 | Coefficient |
| b = -10 | Constant |
| c = 20 | Result |
| Formula | x = (20 – (-10)) / 5 |
| Solution | x = 30 / 5 |
| Final Answer | x = 6 |
Table of Common Equations
Here are some quick examples for better understanding:
| Equation | a | b | c | Solution (x) |
|---|---|---|---|---|
| 2x + 4 = 10 | 2 | 4 | 10 | 3 |
| 3x + 9 = 24 | 3 | 9 | 24 | 5 |
| 4x – 8 = 12 | 4 | -8 | 12 | 5 |
| 6x + 3 = 21 | 6 | 3 | 21 | 3 |
| 7x – 14 = 0 | 7 | -14 | 0 | 2 |
