First of all, this Juan-dude is very generous. I would keep that candy to myself.
Anywho.. In an appropriate equation let on the LHS of the equation, x denote the number of students since this is unknown from the description. When writing the equation it could help to denote the event of giving one tootsie roll to every student as 1 * x (out of lazyness we often omit the 1 in cases like this). Further since there are 9 leftover rolls we should add those to the 1*x on the LHS. On the RHS of the equation we put the total number of rolls, effectively making the equation look like the following.
1 * x + 9 = 63 or x + 9 = 63
