-2(5y-20) - 5y = -5
-10y + 40 - 5y = -5
-15y + 40 = -5
-15y = -45, y = 3
x = 5(3) - 20
x = 15 - 20, x = -5
Solution: x = -5, y = 3... or (-5,3)

Answer:
hotdogs 3.45
rolls 2.60
Step-by-step explanation:
6h + 8r = 41.5
r=h-.85
6h + 8(h-.85)=41.5
6h + 8h - 6.8 = 41.5
14h = 41.5 + 6.8
14h = 48.3
h=48.3/14
h=3.45
r=3.45-.85=2.6
