Review of Algebra and Equations


Algebra

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

Examples

  • 1. x(x + 5) + 2(x – 7)

  • 2. 4x(x – 9) – (x – 10)


Examples1

Examples:

  • 3.


Equations the danlad procedure

EQUATIONS: The DANLAD Procedure

  • 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


Examples2

Examples:

  • 1. 6(5k – 8) – 20 = 11(2k-3) + 3k

  • 2. -4(3 – 6d) = 9(2d – 2)
