Question

The steps below show the incomplete solution to find the value of x for the equation 7x – 3x – 4 = –1 + 21:

Step 1: 7x – 3x – 4 = –1 + 21

Step 2: 7x – 3x – 4 = 20

Step 3: 4x – 4 = 20Which of these is most likely the next step? (4 points)


4x = 24
4x = 16
4x = 5
4x = 80

Answer 1

Step 1 : 7x - 3x - 4 = -1 +21
Step 2 : 7x - 3x - 4 = 20
Step 3 : 4x - 4 = 20
Step 4 4x -4 +4 = 20 + 4
4x = 24

Answer 4x = 24
