Presentation Transcript

  1. 1 – 4 Solving EquationsExample 1 • Evaluate each expression for the given values of the variables. • 6c + 5d – 4c – 3d + 3c – 6d; c = 4, d = -2 • 3m + 9n + 6m – 7n – 4m + 2n; m = 6, n = -4

  2. Example 2 • Simplify by combining like terms. • 9y + 2x - 4y + x + 7y² • - (j – 3j + 8) + j²

  3. Example 3 • This season, the Easton High School boys lacrosse team averaged exactly 8 goals per game. If there are x lacrosse games in a season, how many goals in total did the team score? How many goals were scored in the 16 – game season?

  4. Example 4 Solve the Equation. 1. 5 – w = 2w – 1 2. -2s = 3s – 10 3. 2(x + 3) + 2(x + 4) = 24 4. 8z + 12 + 5z – 21 5. 7b – 6(11 – 2b) = 10 6. 10k – 7 = 2(13 – 5k)

  5. Example 5 • Is the expression always, sometimes or never true? 1. 6x – 3(2 + 2x) = - 6 2. 4x - 2 = 2(1 – 2x) 3.

  6. Example 6 • 1. Solve for a. ab2+ 2a = 5 • Solve for d cd+ e = 4d + e2
