Question

Charlie solved an equation, as shown below:

Step 1: 5x = 30
Step 2: x = 30 – 5
Step 3: x = 25

Part A: Is Charlie'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 will this equation have? (4 points)

Answer 1

incorrect, in step 2 you have to DIVIDE both sides by 5, not divide one by 5 and substract 5 from the other.
Step 1: 5x = 30
Step 2: x = 30/5
Step 3: x = 6
B) the equation has 1 solution

Answer 2
