: Hi!
I am not sure if I got my answer right. The problem is Transforming Equations: -5+y=8
The answer I got for this was y=3; Basically what I did to solve this was, y+-5-5=8-5. I got three out of that.
Help me; Thank You=) This question is from textbook algebra

Close but no cigar.
Given-5%2By=8
What you want to do is get the y on one side of the equation by itself. That part you got right.
Think of an equal sign as if it is a balance point. Whatever you do to one side of the equation, you must do to the other side.
In this case, in order to get the y by itself, you need to 'get rid of" the (-5).
If you add 5 to (-5), you get 0. But if you add 5 to the left side, you must then also add 5 to the right side.
5+-5+%2B+y+=+5+%2B+8
0+%2B+y+=+13
y+=+13
Get it??
Always check your anwer using the original equation.
-5%2By=8 substitute 13 for x
-5+%2B+13+=+8 simplify
8+=+8+ Which is true, so that value if x is correct
