(07.05 HC)The incorrect work of a student to solve an equation 2(y + 8) = 4y is shown below:Step 1: 2(y + 8) = 4yStep 2: 2y + 10 = 4yStep 3: 2y = 10Step 4: y = 5Which of the following explains how to correct Step 2 and shows the correct value of y? (5 points)Select one:a. The equation should be y + 8 = 4y after division by 2; y = 4b. The equation should be y + 8 = 4y after division by 2; y = 6c. 2 should be distributed as 2y + 16; y = 4d. 2 should be distributed as 2y + 16; y = 8
