  1. 3.1 Transforming Equations:Addition and Subtraction • Objective: To solve equations using addition and subtraction. • Warm – up: Simplify:1) 4 = -2 +x 2) -1 + t = ⅓3) 8 – x = 5 4)

  2. 3.1 Transforming Equations:Addition and Subtraction Solve (but look to simplify too!) Solve. Show all your steps! z – ¼ = ¼ -5 = t – 9 (c + 2) + 8 = 4 2 = 10 + (x – 2) • When you solve, you want to reverse the order of operations and follow: • AS • MD • When you simplify, you want to follow PEMDAS, more specifically, • MD (in any order left to right) • AS (in any order left to right)

  3. 3.1 Transforming Equations:Addition and Subtraction Solve. Show all your steps! -(a – 9) = 1 -(x + 2) = -6 4 – (2 – n) = 2 7 – (3 – m) = 8 • -2 + (1 + p) = 5 • (a – 3) + 19 = 125 • 4 – (1 + x) = 5 • 1 = -2 – (4 – w)

  4. 3.1 Transforming Equations:Addition and Subtraction Solve. Show all your steps! Homework: Pg. 98 Written Exercises #31 – 45 odd • 9 – (s + 7) = 4 • -3 + (15 – x) = 4 • (y – (-8)) + 15 = 7 • x + (-2) = 4
