"Balance is the key to solving any equation"

12+x=20 to do this is that your subtract 12 to make it zero then you subtract 12 from 20 because what ever you do to the 12 you do it to the other number so it is 8. YOU end up with x=8 When you have only one number left you have the answer.

"The goal is to get the variable by its self."

Heres some more

30+x=33

30-30 then 33-30 = 3

21+x=28

21-21 then 28-21=7

x+100=280

100-100 then 280-100=180
