The steps below show the incomplete solution to find the value of y for the equation 4y − 2y − 4 = −1 + 13: Step 1: 4y − 2y − 4

= −1 + 13 Step 2: 4y − 2y − 4 = 12 Step 3: 2y − 4 = 12 Which of these is most likely the next step? 2y = 3 2y = 8 2y = 16 2y = 18

Answer:

You stopped at 2y-4=12

If we add same number to both sides the equation will remain true. For example if we have 5=5, and we add 7 to both sides, we get 12=12 which is also true. Now let's do this with our equation. Add 4 to both sides(to have only y on the left side). We get 2y=16, hence y=8.

Answer. 2y=16
