Jimbo was solving the equation below. What mistake did he make as he moved from step 1 to step 2. Explain the mistake Jimbo made.
Student A solves the equation 5x + 9 -3x = 2(5x+4). Some of the steps are shown below.
Step 1: 5x + 9 -3x = 2(5x + 4)
Step 2: 5x + 9 - 3x = 10x + 8
Step 3: 2x +9 = 10x + 8
Step 4: 9 = 8x + 8
Step 5: 1 = 8x
Step 6: 1/8 = x
Which of the following statements BEST describes what Student A did to get from step 2 to step 3.
