## Review of Algebra and Equations

### ALGEBRA

• Rules:

• Only LIKE TERMS may be added or subtracted

• When multiplying or dividing, use exponent laws

• Distributive Property:

• a(b+c) = axb + axc

### Examples

• 1. x(x + 5) + 2(x – 7)

• 2. 4x(x – 9) – (x – 10)

### Examples:

• 3.

• D – Distributive Property

• A – Add like terms on each side

• N – Numbers on right side

• L– Letters on left side

• A – Add like terms on each side

• D – Divide by the coefficient in front of the variable

### Examples:

• 1. 6(5k – 8) – 20 = 11(2k-3) + 3k

• 2. -4(3 – 6d) = 9(2d – 2)
