  1. Do Now • Turn in HW into tray • Place completed Federal Cards on my desk • Have paper out for notes • Solve the following equations… • Y + 8 = 12 • 7 + f – 21 = -20 • 67 = g – (-36) • Ricky rides his bike 12 miles every day. He stops after 7 miles to rest. How much farther does he have to ride?

  2. 2-6 Solving Equations by Multiplying or Dividing

  3. 1. Dividing to solve • Do the opposite of division • Ex: The United States population in 2005 was twice the population in 1949. Find the 1949 population in millions. • 296 million in 2005 • Check answers by plugging in value for variable • 296 mil = 2p

  4. 4x = 84 • 5r = -20 • -3b = 24 • 96 = -8n

  5. 2. Multiplying to solve an equation • Do the opposite of multiplication • Plug in value of variable to check answer • X = -3 -9 • R = 10 -5

  6. You solve… • -30 = t 20 • S = 54 6
