The work of a student to solve the equation 2(5y β 2) = 12 + 6y is shown below: step 1: 2(5y β 2) = 12 + 6y step 2: 7y β 4 = 12 + 6y step 3: y β 4 = 10 step 4: y = 14 step 5: y = 7 in which step did the student first make an error and what is the correct step? (1 point) a: step 2: 7y β 4 = 6 + 3y b: step 2: 10y β 4 = 12 + 6y c; step 3: 5y β 2 = 2(10 + 3y) d: step 3: 2(5y β 2) = 10 + 3y
