    Step 1: 2(y + 4) = 4y Step 2: 2y + 6 = 4y Step 3: 2y = 6 Step 4: y = 3 Which of the following explains how to correct Step 2 and shows the correct value of y? The equation should be y + 4 = 4y after division by 2; y = 5 The equation should be y + 4 = 4y after division by 2; y = 2 2 should be distributed as 2y + 8; y = 4 2 should be distributed as 2y + 8; y = 2 @eninone

    @hayespurdy 2 should be distributed as 2y+8=4y, y=4. this is correct. as put y=4 in lhs and rhs. you get lhs=rhs. not in any othr case.
