UNIT (MAIN IDEA) OF THE NEXT FEW WEEKS:
Algebra - The language of math.
NEW YORK STATE STANDARDS:
5.A.5 Solve and explain simple one-step equations using inverse operations.
6.A.4 Solve and explain two-step equations involving whole numbers using inverse
operations
LESSON GOAL: We will be able to solve for equations involving one-step and twostep inverse operations.
IMPORTANCE?
Props to Amanda,
Jorge, and Sammy for
answering their exit
tickets correctly
yesterday!
To help your grade Mr. Loeb will be collecting your Smartboard notes each day and returning them graded the
next
day. Each day, you will earn a 0% or a 100% on your note-taking. If you take all the notes with the class, you will
earn a 100%. At the end of the week, all of your note-taking grades will be combined together for one class work
grade.

YOU TRY - Solve these equations using the inverse
operation
a) 5t = 10
b) y = 5
2
Inverse Operations: 4
With two-step operations, there are (you guessed it) __________________
steps.
You must always do the addition or subtraction step ____________________.
Then you can complete the multiplication or
______________________________.
EXAMPLE:
(Just do the addition or subtraction step for now)
3x - 3 = 18
Inverse
Operations:
5
YOU TRY - For the following two-step algebraic equations, only complete the FIRST
step
i) 4 + 5x = 29
ii) r/4 + 3 = 14
b
Inverse Operations: 6
Once you complete the first step, you can then complete the
____________________ step.
EXAMPLE:
6p + 7 = 19
Inverse Operations: 7
i) 4 + 5x = 29
ii) 9c - 2 = 34
iii) r/4 + 3 = 14
