Allow me to clarify, rule #1 is whatever you do to 1 side you do to the other so, to solve this equation, you must set it up a 5 = 8 + y. First we must get the Y by itself so in order to do this we must eliminate the 8 so, using the rule, we must now subtract 8 from each side ( Since 8 - 8 = 0 aka eliminated ) So, 5 = 8 + y

                                                                                         -8  -8 

                                                                                         -3  =(eliminated ) y

 So all we have left is -3 = y which gets us our answer but if you want me to put it in terms more basic it would be y = -3, you can prove this by adding 8 to y ( -3 ) and seeing if you get 5, if you do both sides are equal so your overall answer is Y = -3.

Oh! my bad, I had, what people now call it " a blonde moment."....

 

 5=8+y

we want to get "y" by it's self, Yes? YES :)

So, What I think we do is...

minus 8 from 5, which will give yea...

-3,

Divide y by -3 and you get..

Y=-3

:D
