Exit Ticket| Solve Equations with Variables on Both Sides

What is the first step you should take to solve this problem?

-3(x - 2) = -8 +9b

• add 8 to both sides

• subtract 9b from both sides

• Distribute -3 to the x and -2

Which of the following steps would NOT be a correct step towards solving the equation below:

 $-14x\ -\ 7\ =\ 3x\ +\ 2$  

• Combining  $-14x$  and  $3x$  to get  $-11x.$  

• Adding 7 to both sides of the equation.

• Subtracting 2 from both sides of the equation. 

• Subtracting  $3x$  from  $-14x$  to get  $-17x.$   

What mistake, if any, did this student make?

• S/He needed to subtract 3x from both sides

• S/He needed to drop down a +2 instead of a -2

• S/He did not divide correctly

• No mistakes; x=2 is correct
