What should be done to both sides of the equation in order to solve y - 4.5 = 12.2?

maw [93]

Y - 4.5 = 12.2

your solving for y which means your trying to get rid of 4.5 so that y can equal something. The opposite of -4.5 would be +4.5, so you would add 4.5 to both sides to get

y = 16.7

So your answer would be

A. Add 4.5

and also dont' say your stupid because all you need is a little explanation and you'll get it, its very easy you just need to take the time to practice :-)
