What should be done to both sides of the equation in order to solve y + 8.5 = 17.2?
Amanda [17]

Answer:

Subtract 8.5

Step-by-step explanation:

To solve the equation, y has to be isolated (only y will be on one side of the equation)

To do this, we have to get rid of the 8.5, so it has to be subtracted from both sides.

So, the correct answer is subtract 8.5

Anestetic [448]

Answer:

Answer: 9

Step-by-step explanation:
