One brand of suntan lotion comes in a small size with x ounces of lotion and a regular size with y ounces of lotion.  Given the equations below how can we eliminate the terms with x?
x+2y = 15
2x + y = 19.5

• subtract the two equations from each other
• multiply the second equation by -1 and add the two equations
• multiply first equation by 2, multiply the second equation by 1 then add them
• multiply the first equation by -2 then add the equations together
