The way I'd do this is by elimination. Multiply 4x+y=-10 by -14x+4y=20-4x-y=105y=30y=6
As for x multiply 4x+y=-10 by -4
4x+4y=20-16x-4y=4012x=60
x=5
The answer is 360 million or 720 million cells after 4 hours of doubling.
7 pounds = 16 pounds and 1 pound = 6 pounds and 16 ounces.
(6 pounds + 16 ounces) minus (5 pounds + 10 ounces) = 1 pound + 6 ounces

Subtract the cost of the pizza from the total:
16.95 - 12 = 4.95
Divide this value by 3:
4.95/3 = 1.65
1 large drink cost $1.65
