What is the first step in solving:

2x + 3 - 5x - 7 = -8x -11 + 7x -23

• 3x - 4 = -x - 34

• -3x + 4 = x + 34

• -3x - 4 = -x - 34

• 7x - 10 = -15x - 12

• -7x - 4 = 15x - 34

Which of the answer choices shows a correct first step in solving the equation:

4(1- x) + 3x = -2(x + 1)

• 4 - 4x + 3x = -2x - 2

• 4 - 4x + 3x = -2x + 2

Find the Error
What error did the student make when solving the equation:
5x + 6 =  66
5x - 6 = 66 -6
5x = 60
5*5x= 60*5
x = 300

• The student subtracted 6 from both sides instead of adding
• Student multiplied by 5 instead of dividing by 5
• Student got the wrong answer when subtracting 66-6
• The student did not correctly eliminate the variable from one side of the equation
