Answer:
x = -2
Step-by-step explanation:
To start, let's add on the first side to get 3x + 6x - 6 = 9x - 6. For the second side, we need to distribute the 4 to get 4(2x) + 4(-2), or 8x + (-8) or 8x - 8. Setting these equal, we subtract 8x from both sides to get x - 6 = -8, and adding 6 to both sides gives x = -2.
Answer:
its not showing up
Step-by-step explanation:
Growth rate = 200% each year
SO population becomes twice in each year
After 20 years, population = 5* 2^20 = 5242880
(Assuming no deaths occur)

2x-3y=12
2x-12=3y
y=2/3*x-4</span>
