well, there is a bunch of ways, but heres the way I do it
for example X+3=6
in order to make X be alone (which he likes ) you have to get rid of the 3. However, then the equation would be unbalanced. Therefore, you must also get rid of 3 on the other side. Heres a rule
WHAT YOU DO TO ONE SIDE, YOU DO TO THE OTHER
heres what that looks like
X+3-3=6-3
now simplify it
X=6-3
can you do it from here?
