The work of a student to solve the equation 3(3y β 8) = 10 + 3y is shown below:
Step 1: 3(3y β 8) = 10 + 3y
Step 2: 6y β 5 = 10 + 3y
Step 3: 3y β 5 = 10
Step 4: 3y = 15
Step 5: y = 5
In which step did the student first make an error and what is the correct step?
Step 2: 9y β 24 = 10 + 3y
Step 2: 6y + 11 = 10 + 4y
Step 3: 6y β 8 = 3(6 + y)
Step 3: 3(3y β 8) = 7 + y
