+-27+=+x+%2B+24+
Think of the = sign as a balance point, and everything
on the left side has to balance everything on the right side.
----------
That means if you change the right side, you've thrown it out of balance
and now you have to do the same thing to the left side.
-----------
If I subtract +24+ from the right side, then I have to do the same to the
left side, so
+-27+=+x+%2B+24+
+-24+=+-24+
Doing this subtraction, I get
+-51+=+x+ answer
------------------
Then you can check by putting the answer back into the equation
+-27+=+-51+%2B+24+
Doing the operation on the right, I get
+-27+=+-27+
The equation is still balanced, so my solution was correct.
Hope this helps
