  1. Happy Monday…Quick Check …AKA QUIZ!!!! Use Distributive Prop and Simplify (4+3)3 2(x+3) -2(x+3) 3x +2y+4y x+ 3(x+4y) 9+ 2a+3b- 5a Solve for the variable 7. y+7=21 8. m+10=-2 9. k-6=13 10. 19= g-5 YOU CAN DO THIS!!!

  2. Solving Equations By Multiplying or Dividing Monday, November 2, 2009

  3. Division Property of Equality • Words…… • Symbols • When you divide each side of an equation by the same nonzero number, the two sides remain equal. • For any number a, b, c, where c 0, then a/c = b/c

  4. Check it Out!!! • Example: • 3x= -12 • 3x= -12 • 3x = -12 • 3 3 • X= -4 Divide the right side, by the same (3), to balance. Divide the left side of the equation by 3 to undo the multiplication 3 x

  5. Multiplication Property of equality • Words • Symbols • When you multiply each side of an equations by the same number, the two sides remain equal. • For any number a, b, and c, if a = b, then ac=bc.

  6. Check it out!! • Example X = 7 6 • X = 7 • 6 • (X) 6= (7)6 • (6) • X=42

  7. Solve • Y = -9 • -4 • Y = -9 (-4) • -4(-4) • Y= -9(-4) • Same sign=positive • Y= 36

  8. Do Work!!! • In ya’ll textbooks .. • Page 117 • We are doing #1-10 as a family …. • Page 118 • #11-38 • Ya’ll are on your OWN!!!! HAHAHA How cute!!
