Algebraic Thinking Formulas — Class 6 IB MYP

Introduce variables, write simple expressions, and evaluate expressions for given values.

Key Formulas

Variable Expression

\text{Expression using letters: } 3x + 5

Evaluating

\text{If } x = 4, \text{ then } 3x + 5 = 17

Like Terms

3x + 5x = 8x

Worked Examples

1Using: Linear Equation

Solve 3x + 5 = 20.

Step 1: 3x = 20 - 5 = 15.

Step 2: x = 15 / 3 = 5.

Answer: x = 5

2Using: Algebraic Identity

Expand (a + 3)^2.

Step 1: Using (a + b)^2 = a^2 + 2ab + b^2

Step 2: = a^2 + 6a + 9.

Answer: a^2 + 6a + 9
