The intersection of the steps is just a fancy way of asking wi\hich numbers are in both equations so lets look and see :)
The 1st = 0...1...5...7...8
The 2nd =0........5...7........9
 Answer = D {0, 5, 7}
Hope this helps have any questions let me know :)
        
             
        
        
        
Answer:
y = 27.1
Step-by-step explanation:
We have the value of x: 
x = 12 
and we need to find the value of y in the expression: 
y = x + 15.1
as we can see by the equation, the value of y depends on the value of x.
thus, we substitute x = 12 on the previous equation: 
y = 12 + 15.1
y = 27.1
the value of y is 27.1
