Step-by-step explanation:
x + y = 72
x - y = 40
x = y + 40
so, the first equation is then
y + 40 + y = 72
2y + 40 = 72
2y = 32
y = 16
x = y + 40 = 16 + 40 = 56

Step-by-step explanation:
Answer: The unit rate is: " 1.5 patties / bun " ;
or, write as: "1.5 patties per bun" .
_____________________________________________________
The mistake is that the problem shown is incomplete.
The "unit rate" would be the "number of patterns per [single] bun."
_________________________________________________________
30 patties/ 20 buns = 3 pattern/ 2 buns;
= (3/2) patties/ bun = 1.5 patties / bun ;
or, write as: "1.5 patties per bun" .
