One-Step Equations

What is the purpose of solving any equation?

• To isolate the variable.

• To isolate myself from ever having to do math again.

• To subject my brain to cruel and unusual punishment.

• So you can go from "basic" to "extra" and be "lit" and "sick".

What would be the best first step to solving the equation?
-18=m+12

• add 18 to both sides
• subtract 18 from both sides
• add 12 to both sides
• subtract 12 from both sides
