3.) Find three consecutive even numbers with a sum of 72 Warm-Up. 1.) If evaluate 4 – x 2.) Solve for x: 3.) Find three consecutive even numbers with a sum of 72 x = -11 4 – x 4 – (-11) 15 2. Subtract 6 from both sides Multiply both sides by 7 x = -63 (x) + (x + 2) + (x + 4) = 72 3x + 6 = 72 3x = 66 x = 22 The three consecutive numbers are 22, 24, 26.

SWBAT… solve multi-step equations Wed, 8/29 SWBAT… solve multi-step equations Agenda Warm-up (10 min) Review back of agenda problems (10 min) Quiz (30 min) Warm-Up. 1.) Solve for x: 2.) Solve for n:

SWBAT… solve multi-step equations Thurs, 8/30 SWBAT… solve multi-step equations Agenda WU (10 min) 6 examples: multi-step equations Warm-Up: 1.) Review your quiz If you got below the mean (74%), your additional HW is to correct the ones you got wrong and turn it in tomorrow. 7

Mean = 74% Range = 30% -100%

b = 1 1.) b – 8b + 1 = -6 Solve each equation: List the steps: 1. CLT: b – 8b = -7b 2. Subtract 1 from both sides 3. Divide both sides by -7 b = 1 b = 1

m = -12 2.) -(m + 1) = 11 Solve each equation: List the steps: 1. Distribute the -1 2. Add 1 to both sides 3. Divide both sides by -1 m = -12 m = -12

g = 14 3.) 5(g + 8) – 7 = 103 Solve each equation: List the steps: HW#8-Multi-Step Eqns 1. Distribute the 5 2. CLT: 40 – 7 = 33 3. Subtract both sides by 33 4. Divide both sides by 5 g = 14

k = 12 4.) Solve each equation: List the steps: 1. Cross multiply 3(k+3) = 9(5) 2. Distribute the 3 3. Subtract both sides by 9 4. Divide both sides by 3 k = 12 k = 12

x = 1 5.) Multiply both sides of the equation by 6 (each term) To remove fractions from an equation: Multiply both sides of the equation (each term) by the least common multiple (denominator.)
