Review!

Simplify by combining like terms:

4x + 5 + 21x + 7

25x + 5 + 7

25x + 12

4x + 12 + 21x

Review!

Use the distributive property to simplify:

4(2m + 3) + 6

8m + 9

8m + 12

6m + 9

8m + 18

Substituting Values

(Addition & Subtraction)

Which value makes the equation true?

Open Ended

What do you think I need to do to solve for c in this equation?

c + 7 = 11

Type response here

How can I find what the value of c is in this equation?

c + 7 = 11

hint: there are two different ways

Strategy 1: ISOLATE THE VARIABLE

c + 7 = 11

the opposite of adding is to subtract
in order to get the c by itself, we must subtract the 7
whatever you do to one side of the equal sign you MUST do to the other side of the equal sign
ANSWER: c = 4

Strategy 2: MENTAL MATH

c + 7 = 11

ask yourself, what can I add to 7 that will give me 11?
ANSWER: c = 4

Type answer...

Multiple Choice

Which is the solution to the equation?

v + 18 = 23

Multiple Choice

Which is the solution to the equation?

9 + w = 17

Poll

Which strategy do you find easier?

Strategy 1: subtracting or adding each side to isolate the variable

Strategy 2: mental math - asking myself what can be added or subtracted to get my final answer

Substituting Values

(Multiplication & Division)

Which value makes the equation true?

Open Ended

What do you think I need to do to get the z by itself in this equation?

18 = 6z

Type response here

How can I find what the value of z is in this equation?

18 = 6z

hint: there are two different ways

Strategy 1: DIVIDING

18 = 6z

the opposite of multiplication is division
in order to get the z by itself, we must divide by 6
whatever you do to one side of the equal sign you MUST do to the other side of the equal sign
ANSWER: z = 3

Strategy 2: MENTAL MATH (multiply)

18 = 6z

6z is the same as 6 TIMES an unknown value
ask yourself: what number multiplied by 6 will give me 18?
ANSWER: z = 3

Fill in the Blanks

For the equation 24 $\div$ w = 8, what value for w would make this true?

Type answer...

Fill in the Blanks

For the equation 20 $\div$ d = 5, what value for d would make this true?

4s = 32

Type answer...

Multiple Choice

Which is the solution to the equation?

4n = 16

Multiple Choice

Which is the solution to the equation?

8 $\div$ c = 8

Poll

Which strategy do you find easier?

Strategy 1: dividing both sides of the equation

Strategy 2: mental math - asking myself what number can be multiplied by the coefficient

Poll
