Answer: 13
Step-by-step explanation:
Add 3 to each side. That original 3 is cancelled out so you're left with 4x=11. Divide each side by 4 and that leaves you with x = 3.5
Now all you have to do is multiply 4 by 3.5 which is 14. You now have to subtract 1 and your answer is 13.
You have to find the equation that would fit the situation which would be 57,000+800x= population. Then the difference in the years from the year you are trying to figure out to 1980 is plugged in for x. so you would do 2015-1980=35 you would then plug in 35 of x in the equation. 57,000+800(35)=85,000.
