We can get two different equations from this:
3x = 18
and 
3x = -18
So:
x = 6, x = -6
x = {6, -6}

Answer:
4
Step-by-step explanation:
If two variables are proportional then
 
 ...(i)
    ...(i)
where, k is constant of proportionality.
The given equation is
 ...(ii)
       ...(ii)
where,
s = number of cups of seltzer.
c = cups of cranberry juice.
On comparing (i) and (ii), we get
Independent variable:  
Dependent variable:  
Constant of proportionality:  
Therefore, the constant of proportionality is 4.
