🔍 Examples of Equation Solving
Example 1: Linear Equation (ax + b = c)
Let’s say:
a = 2, b = 4, c = 10
Steps:
- 2x + 4 = 10
- 2x = 10 – 4 = 6
- x = 6 ÷ 2 = 3
Result: x = 3
Example 2: Multiplication Equation (a × x = b)
Let’s say:
a = 5, b = 25
Steps:
- 5 × x = 25
- x = 25 ÷ 5 = 5
Result: x = 5
Example 3: Division Equation (a / x = b)
Let’s say:
a = 20, b = 4
Steps:
- 20 ÷ x = 4
- x = 20 ÷ 4 = 5
Result: x = 5
