How are you currently feeling about solving equations? Base your thoughts off of how you did on you asynchronous Quizzizz assignment.

• Great! (I can solve most equations accurately)

• Okay (I know what to do, but I get confused on some problems)

• Meh (I get confused on most problems, and always mess up a step in each problem)

• Horrible (I need to attend tutoring for more help!)

Quiz on Wednesday, 9/30

• We'll take in class.

• If you don't finish, you can finish it on your own.

• It is due by Thursday @ 5:00 p.m. so I can grade it.

Multiple Choice

 $-4x\ -7\ -3x\ +4\ =\ 25$  Do you need to distribute in this problem?

• yes

• no 

Multiple Choice

 $-4x\ -\ 7\ -3x\ +4\ =25$  What would you get when you combine like terms?

•  $-1x\ -3\ =\ 25$  

•  $-7x\ -3\ =\ 25$  

Multiple Choice

 $-7x\ -3\ =\ 25$  What is the next step to isolate x? 

• Remove -3 by subtracting

• Remove -3 by adding

• Remove -7 by adding

• Remove -7 by dividing

Multiple Choice

-7x = 28 How is the - 7 being attached to the x? What is the opposite operation of that?

• Addition

• Subtraction

• Multiplication

• Division

Fill in the Blank

 $-4x\ -7\ -\ 3x\ +4\ =\ 25$  What is the final answer for x in this equation?

Multiple Choice

 $-4\left(7a\ +5\right)=\ -160$  What is the first step to solving this problem?

• Distribute

• Combine like terms

• move all the variable to one side

Multiple Choice

Which of these is correctly distributed?

 $-4\left(7a\ +5\right)$  

• -28a +20

• 28a - 20

• -28a - 20

• 28a + 20

Multiple Choice

 $-28a\ -\ 20\ =\ -160$  What is the next step to solve this problem?

• subtract 20 from both sides

• add 20 on both sides

• divide by -28 on both sides

• multiply by -28 on both sides

Fill in the Blank

What is the final answer for a?

 $-4\left(7a\ +5\right)\ =\ -160$

• Distribute

• Combine like terms

Fill in the Blank

What is the correct distribution of

 $3\left(4w\ -1\right)$  

Multiple Choice

What is the solution for w?

 $-79\ -7w\ =\ 3\left(4w\ -1\right)$  

• w = 4

• w = - 4 

• w = 8

• w = -8

Fill in the Blank

What is the correct solution for y in the equation?

 $y\ -3\left(2y-7\right)=76$  

Fill in the Blank

What is the correct solution for c in this equation?

 $15\ -\ 5\left(4c\ -7\right)\ =50$  

Multiple Choice

Which of these are the correct distribution for the equation:

 $7\left(3r-1\right)-\left(r+5\right)=-52$  

•  $21r\ \ +\ 7\ -\ r\ +5$  

•  $-21r\ +\ 7\ -\ r\ +5$  

•  $21r\ -\ 7\ -\ r\ -5$  

•  $21r\ -\ 1\ -\ r\ +5$  

Multiple Choice

Which of these is the correct combination of like terms in the equation:

 $21r\ -\ 7\ -\ r\ -5\ =\ -52$  

•  $22r\ -12\ =\ -52$  

•  $20r\ -12\ =\ -52$  

•  $20r\ -2\ =\ -52$  

•  $20r\ +12\ =\ -52$  

Multiple Choice

 $20r\ -12\ =\ -52$  Which of these is the correct next step in the problem?

•  $20r\ =\ -64$  

•  $r\ -\ 12\ =\ -32$  

•  $20r\ =\ -40$  

•  $r\ -\ 12\ =\ -1040$  

Fill in the Blank

What is the solution for r?

 $20r\ =\ -40$
