Sasha solved an equation, as shown below:

Question

Step 1: 8x = 56
Step 2: x = 56 − 8
Step 3: x = 48

Part A: Is Sasha's solution correct or incorrect? If the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation. (6 points)

Part B: How many solutions does this equation have? (4 points)

Answer 1

Part A: Sasha's solution is incorrect. In step 2, instead of subtracting 8 from 56, she should have divided both sides of the equation by 8.

Correct steps to solve the equation:
Step 1: 8x = 56
Step 2: x = 56/8
Step 3: x = 7

Part B: This equation has only one solution, which is x = 7.
