Answer:
x = 22,  y = 22/7
Step-by-step explanation:
solve for y using first equation: 
-2 + 3y = 20 
3y = 22
y = 22/7
substitute 22/7 into second equation:
7y = x
7(22/7) = x
x = 22
 
        
             
        
        
        
You need to find the percent of the 125 surveyed students to find the number of estimated students that like pizza.
58/125 = .464 or 46.4%
1500*.464 = 696 students like pizza.
Hope this helps!
