1. Do Now:

2. Section 2.3 Solving Multi-Step Equations
Solve equations involving more than one operation.
Solving equations using consecutive integers.
SWBAT:

3. Definitions Multistep Equation: Consecutive Integers:
An equation that requires more than one step to solve
Consecutive Integers:
Are numbers in counting order:
(3, 4, 5) or (n, n+1, n+2)
Counting by 2 is called consecutive even integers if ‘n’ is even or consecutive odd integers if ‘n’ is odd.

4. Solve Each Equation
1. 11x – 4 = Try on your own: 1. 2a – 6 = 4

5. Real Word Example- pg 92 # 2A
1. A music store has sold 3/5 of their hip-hop CDs, but 10 were returned. Now the store has 62 hiphop CDs. How many were there originally?

Consecutive Integers
Integers that come in counting order
n, n+1, n+2
Consecutive Even Integers
Even integer followed by the next even integer.
n, n+2, n+4
Consecutive Odd Integers
Odd integer followed by the next odd integer.

7. Example (n) + (n + 2) + (n + 4) = -51 (n) + (n + 1) + (n + 2) = 21
1. Find three consecutive odd integers with a sum of -51.
(n) + (n + 2) + (n + 4) = -51
2. Find three consecutive integers with a sum of 21.
(n) + (n + 1) + (n + 2) = 21
