Question

Sasha solved an equation, as shown below:

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 how to solve the equation correctly.

Part B: How many solutions does this equation have?

Answer 1

Part A: Sasha's solution is incorrect. In step 2, she wrote x = 56 - 8, but she made a mistake in subtracting 8 from 56. The correct subtraction would be x = 56 - 8, which equals x = 48. So, the correct solution is x = 48.

Part B: This equation has one solution, which is x = 48.
