C) add 2.9 to both sides

You have to cancel the " -2.9" on the Left side. So add "2.9" to it
      -2.9 +2.9 = 0

However this is an equation, so what you do one one side, you have to repeat the same on the other side as well. 

So add 2.9 to the 5.3 on the right side also

so,  y -2.9 (+ 2.9)= 5.3 (+ 2.9)
          y = 5.3 +2.9
          y = 8.2


Answer : "Add 2.9  to both sides."
