Solving One-Variable Equations

The product of 12 and a number is the same as 2 removed from a number

• 12x=x+2

• 12x=2-x

• 12-2=x-2

• 12x= x-2

Raymond buys bottles of water at $2 each and a large pizza at $13. The total cost was $21. How many bottles of water did Raymond buy?
What is the correct equation to solve?
